A good pipe will increase flow far more than "port matching" ever will.
After spending a decade (uhm.....two) with a (sometimes wet) Superflow 600 screaming in my ears I found finish does nothing to foster increased flow. As long as it has a smooth clean profile there's nothing more you can do. The boundary layer is up to 1 mm thick and cancels anything more than a smooth finish. You should see what a pitot tube does to flow.And that my friends is empirical not anecdotal evidence.
