Yeah, Mike. I now have 3 sets of heads, intake and exhaust manifolds for an '00-'02 V6...one set on the car, one from my old engine and one set I bought off e-bay. I've still got the P&P'd heads sitting in the basement. I was going to swap them out with the old ones when I had the engine torn apart to fix what I thought was a broken valve spring. Unfortunately it was a piston slapping the head that was making the noise that I thought was the valve tapping the piston, and it was cheaper to put a new engine in than tear apart the short block to repair the old one(which had 132,000 miles on it anyway). When I drop the ported heads on the new engine I'll also replace the intake and exhaust manifolds with ones that have been "honed".
I think the better way to go with the exhaust may be to send them to Extrude Hone and have them keep them on their machine a bit longer to enlarge the whole exhaust path in the manifold rather than get a set of haeders made. I'v checked with a couple of custom header fabricators and they all want $100 per port or more to make them. Then you run into issues with the pipes going to the cats needing to be modified $$$. Extrude Hone will do a pair of V6 iron manifolds for under $600.
