Adjusting Roller Rockers
Does anyone know the proper sequence or method for adjusting roller rockers?? It's a new built 351w with Edelbrock Performer RPM heads, Trickflow cam, Crane roller rockers and hydraulic roller lifters. Let me know if you need more info.

found this online...sick of typing
Pick a cylinder.
Bump the motor until the Exhaust valve starts up. Intake is now on base circle.
Loosen the intake lock nut.
WAIT a minute or so, to let the plunger relax.
Twirl intake pushrod between thumb and forefinger (hold gently) and tighten the lock nut until you feel the pushrod stop turning. A little practice is all it takes. You will know - it stops right away, unless you are turning it with pliers. This is zero lash.
Tighten locknut 1/2~3/4 turn.
Bump the motor until the Intake is almost down. Exhaust is now on base circle.
Loosen the exhaust lock nut.
WAIT a minute or so, to let the plunger relax.
Twirl exhaust pushrod between thumb and forefinger (hold gently) , etc...
Tighten locknut 1/2~3/4 turn.
Repeat as necessary.
If you go 1 cylinder at a time, you won't screw up or get confused or need a checklist. There IS a faster way - use it between rounds at the races, or to save time on the dyno. You have the time, go slow and you won't have to second guess after you put the valve covers on.
