Well, I'm far from an authority here but when I took mine in to have them gone through I was told that I had one that was going to need to have .028" shaved to get it "flat" again and that that was too far beyond spec. I ended up buying a used set and had them re-done instead.....and the machine shop only had to remove .004" just to clean them up

The specs are in the Rave CD under the topic Cylinder Head - Overhaul:
5. Check cylinder head height at each end of
head. Renew a head which is outside limits.
a 22.94 mm (0.903 in) - New
b 62.56 mm (2.463 in) - New
6. Cylinder head can be refaced to 0.50 mm (0.02
in) max. below head height.
