I was at an engine rebuilder's place some 20+ years ago and was shocked to see how they "refinished" the mating surface of the heads.
The machine looked like the conveyor belt set up at the check out counter of any grocery store. The belt was a large piece of sandpaper. The guy set the head on, threw a sandbag on top, and then ran it for a few seconds. It didn't seem like anything for precision work although I suppose it might straighten out a head that had some warpage to it.
