Be careful with that, Brian.  I've heard many times now that it's easy to
actually make things worse in that department, if you don't know exactly
what you are doing.  Polishing in particular can actually increase
resistance to flow and lead to drivability problems, because the "as cast"
surface creates a boundary layer that eases air flow, while fuel tends to
stick to the polished surface.
