the camshaft for that particular cylinder. That is the point in the firing order of each cylinder where the
intake valve lash may be adjusted as detailed in Step 5.
Step 7
Adjusting Exhaust Valves: Hand turn the crankshaft until the intake pushrod has reached maximum lift
and is between one half and two thirds of the way back down. This will indicate that the exhaust valve
lifter is at the “base circle” for that particular cylinder. That is the point in the firing order of each
cylinder where the exhaust valve lash may be adjusted as detailed in Step 5.
Step 8
Check for clearances. Always make certain that the rocker does not come in contact the lower portion of
the rocker arm stud, guide plate, or the stud boss of every cylinder. Also, check the clearance between the
spring and the body of the rocker. This should be a minimum of 0.040”. Normally, the smallest amount
of clearance occurs when the valve is closed and the lifter is at “base circle”. Always hand turn the crank
to verify there is proper clearance of the rocker arm throughout the entire travel of the valve.
Step 9
Before installing the valve covers for the final time, check for proper clearance between rockers and valve
covers. Finally, install or reinstall the valve covers on the cylinder heads.
