95 lt1 roller rocker arms

Talk to your local machine shop for advise.

Can you post a picture of the rockers?

I wonder if you used the WRONG non-SA rockers but the tight slots on the iron heads allowed it to function.

If that is the case you will need guideplates and new studs.

You know stock for stock the aluminum heads are NOT an upgrade?

Would like to help. If you can't post pictures I can send you an email addy.

here is a pick they are 1.6 comp cam roller rockers

Can you flip one over or take a profile shot?

What I am looking for is tab that would hold the roller tip on the valve.
Some brands use a washer on either side of the roller tip but Comp ProMagnums have a tab.
I tried to find a picture of what SA ProMagnums look like but no luck finding one.

well i called comp cam they said i need guide plates for these rockers i did not know that.

as I expected

Should be said that Comp guideplates do NOT fit properly. LT1 valve spacing is a little different. Seems like the best "budget" solution is Trickflow. I went a step further with Isky adjustable.
