"um... I thought you knew about these engines....
those ports are PERFECTLY gasket matched to the OEM gasket, which is damn near perfectly matched to the intake ports on the head... its also dirty cause everyone had their grubbys on it before it went into the solvent tank."
Umm yeah.... So you opened the ports up to the exact size of the gaskets. The gaskets are approx. .150 larger than the port openings on the head. A "perfect" (if there is such a thing) gasket match is achieved by opening the intake to .050 smaller than the head port opening. But your right, I don't know anything.....
