Place an adjustable checking pushrod into the lifter and install one intake and one exhaust rocker arm assembly.
Be sure the cam is rotated to the base circle.
Seat the bottom of the adjuster screw into the recess machined in the rocker arm and turn the adjuster screw clockwise 1 to 1-1/2 turns down. This is the initial and optimum adjuster position. Each full turn of the adjuster is approximately .040"
Insert a feeler gauge on the valve side of the rocker arm to set your desired lash.
Use the adjustment on the pushrod to determine the correct pushrod length. If your adjustment requires less than 1 full turn or more than 2 turns you with pushrods you have, you will need a different pushrod length to achieve the correct adjustment. Adjusting outside of this 1 to 1-1/2 turn range will cause incorrect geometry and may also damage your rockers.
