there not all the same but u can go to about 14mm before u run into clearance issues with the top fin.
Top fin can be skimmed to clear or a spacer ring can be used,
compression ratio now thats another issue to think about.

as jj said.
The more you cut you then need to "cc" the heads.
Can get tricky once you have taken away all the easy bits of the head and opend them up.
"most" heads seem to be round the 50cc mark - but you can get them to work either side of this.
Futue te ipsum!!!
