I'm very wary about all this "Smoothing" of things that goes on. Presumably you've got performance in mind with this? One of the factors affecting performance is how well the fuel mixes with the air - slightly turbulent air flow facilitates good mixing and slightly rough castings provide turbulence. Are you aware that Formula 1 engines often have various intake components deliberately roughened to take advantage of this? The point I'm making is that if you smooth everything out you'll often end up with LESS power than you started with!
