Gasket matching vs. port matching.

Gasket matching and port matching are not the same. Is that what you're getting at? You can port match without gasket matching and gasket match without port matching. ....and I reserve judgment on whether gasket and or port matching increases flow until I see results on a flow bench. It's not something I would just arbitrarily say "no it does not" without proof, because I believe in a lot of instances it certainly does, especially if the transition from intake to cylinder head is smoothed out, opened up and made as one.
