    Just take a file and a straight edge and make sure that there is no war-page .And I use either a composite ,and or a copper gasket .With Stage 8 header bolts and or ARP header bolts with lock washers and Loctite. My engine is supercharged with 15 lbs plus of boost.And this seems work for with my Doug Thorley big tube headers,

    That is exactly why I weld all my tubes on the outside, and the flange is milled square!!!!!!
    I want the entire flange clamping down, not that tiny bead!!!!
