I would never use a flexible wheel to clean critical mating surfaces like a head or cam tower, even water pump. Since they are flexible, they do not create a flat surface. They round over the edges and create high/low spots on the surface.
Machine shops use a fly-cutter when resurfacing, but of course that's out of the realm of possibilities when doing most jobs. I simply scrape with a razor blade, then use 120-grit paper on a hard (small) sanding block, then finish with 400-grit. You don't want a mirror like finish on the surfaces, it needs to have a satin look for the surfaces to be pressed into the gasket material.
There's an art to making things flat, some believe in it and some do not.
