Just curious if anyone knows what the horsepower difference between 94 ported exhaust manifold and the old style sccoa header. My friends think the sccoa header will blow away the ported stock because of the 2.5 outlet vs the 2.0 stock. From the postings I read the ported 94 really performs, better than some aftermarkets. I'm currently running the sccoa headers but I have mobile smog check stations where I live. If they pull me over running the headers I'm in for a world of hurt.(The look for every little violation. Then send you off to a smog ref to write off the violations). If the headers only yield 10-15hps gain then I'm going back to ported stock 94 manifolds. Yes I'm running lots of mods making over 300hprw, so flow is important.
Thanks
