I was always under the impression that a polished surface had less heat
transfer than a rough surface. The exterior of the head on our cars
doesn't do much heat dissipation to the air, but it does do >>some<<. I
don't know if the reduced heat dissipation is enough to be an issue, but
thought I'd mention it for discussion's sake.
