I wouldn't go any farther than what's necessary to get the head back into spec as far as the flatness of the gasket surface. Planing excessive material off of the head will increase your compression ratio which would increase your octane requirement at high boost. In other words, increase the compression too much and you may get detonation with pump gas at a boost pressure that you would otherwise be able to run. I've also heard that compression made with boost makes more power than the equivalent static compression. I have never seen documentation to back this up though.
