Just a thought... With the head off, another method to measure the volume of the combustion chamber would be to use something like modeling clay. Carefully press the clay into the cavity of the head, making certain that there are no voids in the clay. Completely fill and level off with a straight edge. Remove the clay and place in a small graduated beaker of water (like you may have used in chemistry class, the smaller the better for accuracy). Measure the amount of water displaced when the clay is submerged. That should get you close. Make sure to install an old spark plug to close the hole. I think this might be a little easier than using a liquid to fill the cavity. Additional corrections can be made to account for gasket thickness and piston configuration as required.
