Just a port. You don't want to polish the IM, that'd be bad. RRM doesn't polish it, either.

Did porting give you any noticable gains? How much did it cost you?

RRM's costs more because they powdercoat it and the porting is done for them by another company. They also maintain a few cores, which isn't cheap. PPI does the porting in-house and doesn't coat the manifold unless you request it, in which case they offer the Swain-tech coating. And again, neither of them polish the runners, that'd be bad, RRM's label saying port/polish is a misprint. You want to leave intake runners unpolished to facilitate a better mixing of the fuel in the air.
