I owe everyone that said exhaust leak an apology. I found a copper turbo gasket a GN guy gave me a few years ago. I put a nice thin bead of copper permatex on both sides and let it cure up some, then yanked the turbo back off and put the gasket on and let it cure up a little more. I never would've though it would make THAT much difference. My SBC does not seem to care that much.
