Yeah, I wasn't very clear on that. If you want a squish band, you first need to mill away the hard corner that R80 heads create in R100 barrels in order to better match the periphery of the piston. Then plane down the head (or barrel) to set desired squish. No, milling out the combustion chamber in and of itself will not give you a tighter squish band... quite the opposite.
