3. DETERMINE CORRECT PUSHROD LENGTH
Place the pushrod length checker into the lifter and install the rocker arm assemblies. Be
sure the cam is rotated to the base circle. Seat the bottom of the adjuster screw up
against the recess in the rocker arm and turn the adjuster screw clockwise one full turn
down. This is the initial adjuster position. Adjust the pushrod length tool to the proper
length, remove from the engine, and measure its overall length.
The rocker arm should not be operated with the adjuster screw more than one turn up or
down, from the initial adjuster position. Doing so can cut off the flow of oil to the rocker
arm.
4. FINAL ASSEMBLY
Place the rocker arm assemblies on the cylinder heads, making sure the intermediate
stands that have the oil gallery are placed over the oil supply hole. Torque the 3/8" nuts to
25-30 foot-pounds and the 5/16" nuts to 20 foot-pounds. After all of the stands have been
tightened down, set valve lash and torque the adjuster screw jam nut to 5/20 ft-lbs.
