I would like to polish the inside of my intake/exhaust ports in my head after I finish the port work. Any suggestions on a compound that I can use?

Yea^ polished intake ports dont tumble the air, also air doesnt flow as well over smooth surfaces as it does on rough ones.
This wrong. Air flows much smoother on smooth surfaces. The problem with a polished intake port is with fuel droplets from a carb (or poorly atomizing injector) will stick, bead up, and than fly off. It makes for inconsistent fueling. The rough surface will allow an amount of fuel to coat the surface, so additional droplets will quickly spread out into the mass, while vaporization removes it, very consistently. So on an injected car thats blasting fuel onto the back of the intake valves, its not that big a deal. But for that matter, polishing either port isn't really worth it either...you can get it "smooth enough" with fine sanding...
