How do I adjust where the tip of the roller rocker is in terms of left to right (not the whole pushrod length thing) Some of the tips should move to to right or left a bit so theyre not hanging off the edge of the stem causing uneven weight distribution on the tip. Do I just loosen the pushrod guideplates and move them either right or left? Thanks

Yep. Make sure that the sealer on the rocker studs is a non-hardening type or you will have to re-seal them. (Make sure that if the studs go through the intake ports that you remove any sealer crumbs that may fall out of the stud holes). The alignment doesn't have to be perfect, you just don't want more than 1/3 of the rocker contact point hanging off the valve tip.

This is usually not adjusted for, it's one of those things with stud mounted rockers. However, you had a thought about adjusting the push rod guide plates and this is a bit on the right track. Isky sells a two piece guide plate, you can use this to offset each push rod to shove its rocker over a little. This will fix the condition if your existing guide plates are the cause of the offset. If the cause is the result of machining discrepancies where the stud and the guide aren't in the same line as the push rod, you can lean the rod a little, very little, to shove the rocker over. You have to watch for binding the push rod in the guide when doing this, which is the limit of your adjustment. Keep in ming that heavy springs will tend to bow or bend a leaning push rod so it this is a full up race engine expect failures of the push rod every so often. Doing this on a ball mounted pushrod can result in the rocker tipping at the valve stem which will wear funny if it doesn't break the rocker out right.

ok, im going to go through every rocker and see what i can do about it, but how do I tighten the rocker nut? It's a nut with a setscrew inside of it. Do i finger tighten the nut until it stops due to the hydraulic lifter spring and then torque the hex screw in the top of it to a certain amount? how many ft. lbs??

and for adjusting see post setting valve lash in engine section

For a 3/8" stud it will take a proper sized allen wrench and a 9/16 box end wrench, Hold the hex nut steady and loosen the allen, it is a locking screw. Then you can adjust your rockers to the proper spec, when adjusted, again hold the hex nut steady and tighten the allen set screw.

oh sorry its a small block chevy

[awoodman]

what torque do I tighten the hex nut to, though? Thats what im wondering

There is no torque spec on small block chevy rocker arms. Do a search on here for valve lash adjustment. Once valves are adjusted properly, then lock down the adjuster.
