Engine Combo Questions

THere are various opinions..For me, I dont polish intakes, I finish with a medium grit stone and flapper, that's it. I perefer to have serious velocity to keep the fuel in suspension. I do think a larger cross section port on a smaller displacement would benefit from a rougher surface, due to low speed issues, but once the engine/port combo is in it's rpm range, I dont think it really matters. I do like to polish the exh side a bit to keep things cleaners longer, and less surface area (smoother) means more heat retained in the gases, instead of dissipating into the head. The advantages should be there, but IMO, there is such a small difference that shape is MUCH more crutial than finish.
