Question on my lower intake gasket - cobra intake, gt40x heads. The gaskets I took off had 2.0x1.2 port openings (I'm guessing a Fel Pro 1250) the new gaskets are Ford Racing M9439-A50 with 2.2x1.28 openings. Sure looks like very little room for error on the gasket match to the manifold. Looks like if I'm off at all the blue ring will be on th edge mating surface. Since the fit is so tight on the Fords, should I go with the Fel Pro? Sure don't want to do this over!!
