Does anyone have any idea how much volume is gained after polishing the combustion chamber of a g-head?

Thanks, that gives me an idea. I'm having a set of heads done. With the stock 69cc volume and the head gasket volume, I will be at least 9.4:1 on compression. They have been milled in the past but I haven't measured how much. It will be close to the upper limit for pump gas.
