Not quite. The crossectional area of the chamber is less than the diameter of the cylinder bore. For example, it takes about .005" milling of the block deck to remove 1cc of volume. It takes .007" milling to remove 1cc from an LS1 head. In THEORY you would lose a little over 2cc head volume, but as TinIndian pointed out, other factors can effect finished chamber sizes.
