I apoligize if this topic is redundant, I dont usually posts
topics already covered, but this one I wasnt sure.


anyway, the car: 89 GTA L98 w/ iron heads
There is no need for machining or installation of new studs to install 1.5 or 1.6 roller rockers?

Im just about to purchase matching roller lifters, rockers
and pushrods for my engine that I just completed 3 days ago. The cam is an excellent TPI cam and will probally respond better if I got rid of the stock lifters,pushrods and rockers.

I wasnt sure if ya need to change anything to the stock iron heads, just wanted to clarify before spending cash.

 

your studs should be fine unless your going with a big lift, then u should get screw in studs and guide plates

Sorry If I posted in the wrong forum ..
