I'm not sure how you determine if more than .20 has been removed if there is not a starting head height. I mean no one would ever buy a milled head. Someone should know what this measurement is. I'd also ask the head shop to thoroughly clean and then magnaflux test the head for cracks before doing any work on it. Cracks are often very small and hard to see to the untrained eye.
