I was cleaning my house the other day and came across some 1.52's rr's I had on my IROC (car came with them), they are the magnum series. I know theyarent the greatest but if it saves me some money right now as most of my car is staying stock (minus the bottem end, and turbo kit). Would these work on my car? I have a 94 Z28 with the 374 castings...Im getting my heads cleaned up, I thought I read somewhere I might need some stuff but when I search I found completely different things

they look like this:

 

Those are "non-self-aligning" rockers so you'll need to add guide plates.

Are these the GP's I have to purchase? Also should I upgrade to a 7/16 stud at the same time?

 

You'll need a 7/16" rocker to run a 7/16" studs. Lokks like your rockers are 3/8"
