Are they the stock style pedestal mount? If so, then you torque them down and you're done.

BENNYJET, YOU HAVE ONE CAM...ONE!!! Now that I'm done yelling, yeah, torque em and go. No need for adjustments like stud mount shit.

lol i don't know why i keep saying Cams. i always mean to say Cam. when i got them off someone, each RR were set differently, the adjuster piece that where the pushrod piece sits. i adjusted them so they are all the same. but yea, i'm just gonna bolt and go

Benny, you have the Comp Cams adjustable pedistal mount roller rockers. Each rocker has an adjustment screw in the pushrod hole, they must be adjusted for your engine! The way I do this is to get each cam lobe on the base circle. I start with the first rocker on the driver side and work to the back, then do the other side the same. Turn the crank until the first rocker stops moving/lifting, then turn the crank 1 full turn. You are now ready to adjust that rocker. Turn the adjuster screw until the lifter plunger starts to move downward, then turn another half a turn & tighten the lock nut. Do every lobe like that and you should be set. This should be done with the intake off, or else you're not going to see the lifter start to plunge.

oh crap, everything is back together. i haven't started yet though. i should be ok to run it like that for awhile?

id ajust them before running if those are the rockers you have, you dont want to burn up a lifter...

If too tight, you'll leave valves hanging open.

thanks for the feedback guys. yea i took it apart and adjusted them. i have to admit, it was WAY out of adjustment. i had that lifter plunger way in there. the only crappy part was 2 of the roller rockers i had a hard time adjusting. when i adjusted it, it was moving the the roller rocker instead of the plunger. any thoughts why it was doing that? i
