Checking Total Cylinder volume

They really don't check total cylinder volume. They will measure a combution chamber volume, piston to deck at TDC, overbore (measured above the ring travel), stroke, and head gasket thickness in several places. The tech sheet specs for gasket and deck will be added together and should be less than or equal to the sum of the measurements of those items on your engine. If you have a Super Stock engine, they may or may not measure the piston to meet spec for dish or dome volume. On a Stock engine, they look for accepted piston identification or OEM piston id for correct application, assuming that an accepted piston will be correct for dish or dome volume.
