RR's
 

Since I'm in school right now and I just bought a winter vehicle, I dont have a lot of cash to spend on my Z28 right now. I was thinking about getting a set of 1.6 roller rockers. The only mods I have are in my sig. What do you think my gains will be with these compared to stock and what are the best kind? Also, If I plan on installing a CC306 cam this spring- do you think those rockers would get too much out of the cam to make it not very streetable?? Thanks guys.

No it shouldnt make the cam less streetable. I will just make the lift #'s a little bigger, which makes the cam slightly bigger. I would say however that it might be a good idea to wait until you have better springs on the car. Another thing that youll have to do is decide if you want to use aligning, or non self aligning. Non self aligning is what i have and it is supposed to be better, however you have to use guideplates with hardened pushrods.

Just looking at your sig i would vote for some headers for sure before i would worry about 1.6RR.
