If you are .005 below deck height with your piston, you would add that amount of volume in cc's to your head chamber to be correct. It would be considered opposite of a dome piston where you would subtract the dome volume from the head volume. Another way to do it would be to add gasket thickness to equal what your deck height to piston would be and make up for that thickness in thousandths. Thats probably the easiest way. It will get you really close if you do some minor figuring and plug in the values. Hope this helped.
