Default Adjusting Lt4 roller rockers

How many turns past 0 lash for lt4 roller rockers with poly locks? I went 3/4 turn!? I have 3/8 arp rocker studs, comp 850 lifters. Keeping rpms below 5500 most of the time so i was hoping that 3/4 turn would keep valvetrain noise down. I know 1/4 to 1/2 turn is better for high rpm performance. Cam is a 215/224 with .533 lift.

3/4 turn is fine. FSM says 1/2 to 1 1/2 turns. Many do 3/4

I did 3/4 when adjusting mine during the rotate the engine by hand method. Seems ok, but the car has no mufflers at the moment so hard to tell.
