I disagree. You may "gasket match" - to a free gasket - and you are not required to do it to both sides. For my particular car, it is irrelevant anyway. The factory 4AG engine has the "TVIS" (variable induction butterflies) plate between the head and the intake. It has been decreed by the tech department that it is not legal to modify or remove it (since it's neither part of the head nor the manifold), so doing anything other than cleaning up the (few and minute) casting dags to 1" in is pointless. Not to mention that the intake runners in a 4AG are too big in the first place.
