If you wanted to reduce the compression to, say, 10.4, that's a clearance volume of 16.31cc.
Take the difference between those, then divide by the area, would give a theoretical ~0.85mm of head lift needed.
***BUT as stated so excellently by Gavin, the CR numbers are not to be trusted. Measure your unswept volume empirically. I just felt like doing maths to keep my hand in...

Thanks mockery, but that formula doesn't seem quite right to me? I don't have a lot of time ATM, will look again when I get home.
Cheers guys
