I have a 95 Z28 and i got a 58mm throttle body and headers that are going to be installed. However, i am going to have to get the intake manifold ported with 58mm holes for the throttle body and portmatch the manifold outlets as well. If I had all that done, should I have the heads ported as well, buy a set of performance heads and if so which ones, or is not not that big of a deal to have the heads done. Thanks for your help!

 

Heads will help. You need to get a cam in there to. The heads will compliment the cam and vice versa. AFR are some really good heads, but if you are on a budget, I would just get them ported/polished.
