Andy , is it safe to assume that you at least cleaned up the ports to match a gasket?

I just had a set of those manifolds you used and plopped the gaskets that come in the standard fel pro gasket set on them, 452 heads ported by Dwayne Porter, good thing I did because the end ports on the manifold were close to an 1/4 inch narrower than the gasket which was the size of the exh port opening on the heads ...
