I think I'm gonna try to put my stuff on now. Headers, rockers and intake. I will hold off on the MAF (and the injectors) cause I might have the wrong one (no flange for the 95).
I am gonna get a fuel pump regulator cause I already know I'm running a little lean and will get a bigger fuel pump and the right MAF and do these four things the second time (inj, maf, pump, reg). Then finish up my exhaust. Hopefully I will have it all done before Santa arrives.
I'm gonna run with stock heads and cam for a little longer and swap those out this summer.
Its a tough call for you. Personally I'd like to do the mods before the heads to see what the car will do with stock heads, cam and bottom end. Then swap around the internals and see what that alone does for my car. Just depends on what you want I guess?
