.0007” to .0012”. Use JIMS No. 33443 84 Tappet Block Alignment Tool.

4. If the pushrods you are using are adjustable, proceed as follows.
5. With the Steady Roll Tappet installed, start with the front tappet at the lowest point on the cam,
extend the pushrod to zero lash (no up and down play, but has a light spin.)

cations supplied with the pushrods used. Tighten lock nut. Repeat this procedure for the intake
pushrod.
Note: Popular pushrod adjustments listed below.
Important Note: This adjustment will make the pushrod tight, which will bleed down the hydraulic
lifter. It can take 5 15 minutes to bleed off completely.
Caution: It is very important that the engine is not rotated while the pushrods are tight. The pushrod will spin
with your thumb and forefinger after the tappet has bled off.

hydraulic plunger .100” below the retaining ring and pushrod seat.
