I would assume the minium to get the head/deck true. Then pick your headgasket, not the other way around.
This.

Tell them to take off the minimum they can while still getting you a perfect sealing surface. Then get the numbers for what they took off and use that to calculate your head gasket thickness.

If you've got the wrong one, sell it and order another one.
