so you have access to a flow bench and tons of time for r&d? without access to a flowbench you are probably wasting time and actually decreasing flow. you do not want to polish your intake manifold runners because you will loose all your turbulence and at the same time make the a/f mixture not as mixed and vaporized. the only thing you want to polish is your combustion chamber to reduce the chances of getting hot spots from carbon build up. port matching on the other hand is benifcial.

Just do gasket matching.

gasket and port matching sounds like the best/cheapest thing to do.
