Prw stainless rockers

i dont think PRW is making the SS rockers anymore but i could be wrong. I use them. you MUST correct your geometry anytime you use nonfactory parts.

Call B3 racing engines and talk to him. Dont matter whose rocker you use, you need to correct the geometry. And not with thin shims.

I doubt any serious engine uses an aluminum rocker any more. It was easy to machine and cheap when they started. A steel rocker is much better. And needle bearings on a reciprocationg shaft???? Only chevy would do that and be able to sell it.
