I use foil balls to to get the actual dimension above the piston, have them milled to bring them (a little too) close, and then check them again and use a die grinder to bring everything to where I want it.

I will admit that I have not done this with stock iron heads, but I have done 3 sets of aluminum heads and it worked well.
