INSTALLATION INSTRUCTIONS

STUD MOUNT ROCKER ARM
INSTALLATION INSTRUCTIONS
Adjusting-Scorpion-Rockers

Please read these instructions and notes carefully and completely before beginning.

Removal of the OEM Rocker Arms:

This should be done one cylinder at a time with extreme caution. You must make sure each valve is completely closed before removing the rocker bolt.  Failure to do so could result in damaging the threads.
After removing the old rocker arms, closely examine the ends of your old pushrods for wear. Also check the pushrods for straightness.
Scorpion recommends using new pushrods with new rocker arms to ensure proper mating of the pushrod end to rocker arm cup.

Trial Fitment:
Remove one rocker from the box for trial fitment on all valves. If you
have a fitment issue, resolve it prior to installing all the rockers on
the engine. Once you install all of the rockers they cannot be returned or exchanged. If you have any questions please contact Scorpion Technical Support at 352-512-0800.

Some areas to check would be:

1 – Pushrod length
2 – Interference between the rocker and any of the surrounding
components (valve spring, retainer, rocker stud, valve cover, etc.)
3 – If other than stock ratio rockers are used check for pushrod to cylinder head and guide plate (if used) clearance. Also check that
there is no spring bind, retainer to seal or piston to valve interference due to the added lift.

Installation Instructions:

You will install and adjust one rocker at a time and on one cylinder at a time always  turning the engine in the normal direction of rotation.
Rotate the engine until the exhaust pushrod is all the way down, continue rotating until it just starts to move upward. Stop, lubricate, install and adjust the intake rocker (see adjustment section below).
Then rotate the engine until the intake valve is open and then just
closes. Stop, lubricate, install and adjust the exhaust rocker. You will continue this procedure cylinder by cylinder. This procedure will work on any engine with a camshaft.

Adjustment Recommendations:

Hydraulic:

Turn the locking nut down with your fingers while lightly moving the
pushrod up and down (using very slight pressure). When there is no
more up and down pushrod movement that is “zero” lash. From
there tighten the nut ¼ to 1 turn down (lifter preload) and lock the set screw in place. If it is an aftermarket cam and lifters follow the manufacturers’ preload instructions. Do not go back and check your
adjustment as it will seem loose due to lifter bleed down.

Mechanical:

The amount of valve lash used is determined by the cam lobe design
and is not determined by the rocker. This means the only person that knows the correct valve lash on a particular mechanical flat tappet or mechanical roller cam is the camshaft manufacturer. After installing
the rocker as outlined above use a feeler gauge to set the lash.
Using the correct size feeler and another .002 thicker. After setting the lash to the correct setting, take the .002 thicker feeler and make sure it doesn’t fit. The above engine positioning and this lashing
procedure will ensure the lash is correct and repeatable. If using a valve train stabilizer (stud girdle) make sure correct lash is
maintained after installation and there is no contact between the stabilizer and the rockers and the stabilizer nuts and the rockers.

Rocker Arm Adjusting Nuts:

The set screw locks the adjusting nut in place. Tightening the set screw while holding the nut with a wrench is the correct installation.
After this is done you can lightly “bump” the wrench holding the nut to tighten the nut and help seat the set screw. Do not overtighten as
the nut or stud can be damaged. While some people look for a
torque setting on the set screw, the above is the accepted procedure.
We do not recommend using thread locking compound on the set screw. If you are experiencing loosing of the adjusting nut it is
usually caused by an irregular surface on the top of the rocker stud
allowing the set screw to only contact a small area.

IMPORTANT:

• Any component changes to the valve train (camshaft, valve length,
etc.) or machining to the engine block or cylinder heads will affect
the results of this procedure.
• On engines that have aggressive camshafts, high spring loads and
5/16” diameter pushrods, Scorpion strongly suggests the use of .120” wall pushrods. .120” wall pushrods are also highly recommended for engines with 5/16” diameter pushrods over 8 inches in length. The added stiffness will produce power gains and increase
stability and durability throughout the valve train

NON-ADJUSTABLE PEDESTAL MOUNT ROCKER ARM
INSTALLATION INSTRUCTIONS

Scorpion Race Series 1.7 Rockers on Head

Please see specific instructions inside your rocker arms box.

Please read these instructions and notes carefully and completely before beginning.

Removal of the OEM Rocker Arms:

This should be done one cylinder at a time with extreme caution. You must make sure each valve is completely closed before removing
the rocker bolt. Failure to do so could result in damaging the threads.
After removing the old rocker arms, closely examine the ends of your old pushrods for wear. Also check the pushrods for straightness. Scorpion recommends using new pushrods with new rocker arms to ensure proper mating of the pushrod end to rocker arm cup. If your engine has factory rocker arm stands, the stands will not be used.

Trial Fitment:

Remove one rocker from the box for trial fitment on all valves. If you have a fitment issue, resolve it prior to installing all the rockers on the engine. Once you install all of the rockers they cannot be returned or exchanged. If you have any questions please contact Scorpion Technical Support at 352-512-0800.

Some areas to check would be:

1 – Pushrod length
2 – Interference between the rocker and any of the surrounding components (valve spring, retainer, rocker stud, valve cover, etc.)
3 – If other than stock ratio rockers are used check for pushrod to cylinder head and guide plate (if used) clearance. Also check that there is no spring bind, retainer to seal or piston to valve interference due to the added lift.

Installation Instructions:

Working on one cylinder at a time, watch the intake pushrod while rotating the engine in the normal direction of rotation. When the pushrod moves up and then all the way down (intake valve just closes) install the exhaust rocker. Make sure the radius on the pedestal mates with the radius on the rocker fulcrum – the flat on the fulcrum goes up against the head of the attaching screw. Lube with
Scorpion Cam & Lifter Installation Lubricant (part numbers AL4-1 or
AL8-1) and lightly snug the rocker arm attaching screw with your fingers 
until the up and down looseness of the rocker is taken up (zero lash). Setting your torque wrench to 18 to 20 ft.lbs., turn the screw until the torque is reached. The screw should turn one half to one full turn between zero lash and torqued. This will give the proper lifter preload. If there is less than one half turn, a longer pushrod is needed. If there is more than one turn, shimming of the rocker stand or a shorter pushrod is needed. Scorpion Racing Products offers shims in .020” thickness, part number 3220SM (32 pieces).

To install the intake rocker arm, rotate engine in the normal direction of rotation until the exhaust rocker just starts to move up (exhaust valve just starts to open). Now install the intake rocker arm using the same procedure as used on the exhaust rocker arm above. Continue cylinder by cylinder until your installation is complete.

NOTE: Always use a quality assembly lube such as Scorpion Cam & Lifter Installation Lubricant (part numbers AL4-1 or AL8-1) on all moving parts.

IMPORTANT:

Due to attaching screw diameter, maximum open valve spring
pressure is 420 lbs.
• Any component changes to the valve train (camshaft, valve length, etc.) or machining to the engine block or cylinder heads will affect the results of this procedure. • On engines that have aggressive camshafts, high spring loads and 5/16” diameter pushrods, Scorpion strongly suggests the use of .120” wall pushrods. .120” wall pushrods are also highly recommended for engines with 5/16” diameter pushrods over 8 inches inlength.

3 – If other than stock ratio rockers are used check for pushrod to cylinder head and guide plate (if used) clearance. Also check that
there is no spring bind, retainer to seal or piston to valve interference due to the added lift.

Checking for Pushrod Length:

Pushrod length is correct when the adjustment screw is out anywhere
from one half to two turns from the adjuster being bottomed up into
the rocker when the rocker is at the correct adjustment.
Forcibly bottoming the adjuster into the rocker or having the adjuster
past two turns out could cause a failure.

Installation Instructions:

Lube all rocker arm components including the adjuster threads with the supplied high pressure lube. Working on one cylinder at a time, watch the intake pushrod while rotating the engine in the normal direction of rotation. When the pushrod moves up and then all the way down (intake valve just closes) install the exhaust rocker. Make sure the radius on the pedestal mates with the radius on the rocker fulcrum, the flat on the fulcrum goes up against the head of the attaching screw. Install and torque the attaching screw 18 to 20 foot pounds. The attaching screw must not be installed or removed with valve spring load against it.  At this point you can also perform your exhaust valve adjustment.

NOTE: Maximum adjuster locknut torque is 22 foot pounds.
To install the intake rocker arm, rotate engine in the normal direction of rotation until the exhaust rocker just starts to move up (exhaust valve just starts to open). Now install and adjust the intake rocker arm using the same procedure as used on the exhaust rocker arm above. Continue cylinder by cylinder until your installation is
complete.

IMPORTANT:

Maximum valve lift is .650”.
Due to 5/16” dia. attaching screw, maximum open valve spring
pressure is 420 lbs.
• Any component changes to the valve train (camshaft, valve length, etc.) or machining to the engine block or cylinder heads will affect the results of this procedure.
• On engines that have aggressive camshafts, high spring loads and

Scorpion Racing Rocker Arms Shaft Mount

SHAFT MOUNT ROCKER ARM
INSTALLATION INSTRUCTIONS

For Chevrolet, Small Block Chrysler, Ford, Oldsmobile and
Pontiac applications.

Please read these instructions and notes carefully
and completely before beginning.

Follow these instructions closely for easy installation.

If you have any problems please contact Scorpion Technical Support
at 352-512-0800.

CAUTION: DO NOT install or remove these rockers with valve spring load present or damage may occur.

Installation Notes:

• Aftermarket valve covers may be necessary.
• Lube pushrods and adjusters with the provided Extreme Pressure
Lube #3.
• Tighten all fasteners and adjuster nuts with a quality, calibrated torque wrench.
• Check cylinder head rocker stand bolt holes for proper threading
and depth.
• Check head bolt or head stud / nut clearance to underside of rocker stand.
• Check cylinder head for pushrod clearance throughout the lift
range.
• Due to the type of cylinder head and the components used,
cylinder head machining may be necessary in some cases.

Installation Instructions:

1. Adjust Stand Height
The proper stand height is determined by the roller tip being centered on the valve tip. This can be accomplished by putting black
marker on the valve tip and installing the rocker stand, pushrod and rocker assembly with no lash. Then rotate the engine so the valve travels though the lift cycle, remove the rocker to see the pattern left  in the black marker.  If the stand is too low the mark on the valve will be off center toward the intake manifold, so add shims accordingly. If the stand is too high the mark on the valve will be off center toward the exhaust port, so a longer valve, lash cap, or cylinder head machining would be necessary.

2. Attach Stand
The rocker stand mounting holes have a small amount of elongation. Loosely attach stand (with provided lube or sealant on the attaching screws) and rockers to obtain the best front to rear stand position.  Remove rockers and torque stand (see included torque spec).

3. Adjust Pushrod Length
Pushrod length is correct when the adjuster is from ¼ to 2 turns out from the fully seated position. This is determined after rocker stand height is established. DO NOT use force when seating the adjuster.

4. Install Rocker Arms
Lube the adjusters and pushrods with the provided Extreme Pressure Lube #3. Lube the attaching bolts with 30-weight motor oil and torque to the proper spec. Install rockers one cylinder at a time with the lifters on the base circle of the camshaft and the adjusters turned up enough so there is no spring load on the rocker.

IMPORTANT: Torque Specifications

• 7/16-14, T50 six-lobe stand attaching bolts on aluminum heads
60-65 ft. lbs. with high quality moly lube or sealant
• 7/16-14, T50 six-lobe stand attaching bolts on cast iron heads 60-65 ft. lbs. with high quality moly lube or sealant

• 5/16-18, T45 six-lobe rocker shaft attaching bolts 24-26 ft. lbs. with
30-weight motor oil
• 12-point adjuster lock nuts 18 ft. lbs. minimum to 20 ft. lbs. maximum
with the provided Extreme Pressure Lube #3
