I am going to fabricate a set of stainless steel headers for my GMC 302 straight 6. I manage a tube bending shop, so the bending will be easy, but I am having trouble finding someone that makes a nice stailess steel header collector. I plan on running 1 5/8" diameter tubes off of the engine, then down into a 2 in 1 collector that dumps into my 2" diameter exhaust. Since the 302's have only 4 exhaust ports, I plan on bringing two groups of two, into the collector, then into duel exhaust. Any suggestions to find these off the shelf would be great, otherwise, I will fab them from scratch.
Thanks
