im gonna be installing my lt4 valve springs and comp cams 1.6 roller tip rockers this weekend, i prefer adjusting them while the car is running, do i want to tighten them untill the "clack" is gone or should i go 1/4 turn right after the clacking has stopped,

 

you should pull the coil wire and do it, it really works better. plus if you havent ever done it b4 you might want to take it to someone that knows what there doin. there is alot of power loss in the valvetrain. but if you jus wanna do it you got to find what they call zero lash. I cant remember exactly how that works but maby someone else will chime in.
