You guys are kidding me right? So when I rebuild my slant six, add a new intake and exhaust system, I should have it all milled up and use the high temp copper sealant I used on things like fuel pumps on their gasket surfaces and that's enough? I've never heard of not using a gasket on the exhaust manifolds....
