I've never seen any engine with the internals polished even motors designed for only racing. Smooth surfaces usually aren't conducive to flow of fluids and can cause puddling and beading. A easy example is to look at the bottom of a boat, they are generally coated with a semi rough material to help reduce friction. You want a semi rough surface its good for flow and fluid movement.
