Thanks for blazing the trail for the rest of us. I have RD stainless headers and exhaust also (resonator and muffler). There were some questions a while ago about mating the headers to the cylinder head. The head has square ports, but the headers are round correct? What did you use for a gasket and did you try to port the header inlets at all?
Thanks for the tip about flaring the pipes, that is sure to save me time and a few swear words.
