Still planning to shave them, huh?

Well, the way you determine how much is needed is not by guessing. Your
machine shop will have a precision straight edge that can be placed along
the mating surface of the head in different directions. In combination with
a set of feeler gages, they can tell if and how much the head is distorted.
Also, when the head is milled, they don't just take it all off at once. They
can take a couple passes over it and tell as they go when "enough" has been
reached. But if they need to take much off to get it flat, your head is
toast and you're wasting your money.

Also, about those gaskets - do you see that there is some doubt in the minds
of your fellow SHOtimers that the copper gaskets are the way to go?

Regards,
