Well, I've done the copper silicone and no gasket thing.....not ideal. No I did not machine the exhaust side of the heads, nor did I machine the header flanges, just was out of the question. The stock fel pro metal looking gasket, down right SUCK. the felpro 1400's work good, but everytime I took the headers off, they would eventually flake away, and leave behind gasket material on the heads and headers. So the question I was asking, really wasn't answered, but its alright. I'll just go for the gasket with bigger ports, and hope they are not TOO big?
thanks a bunch.
