Rich,
How do you mean 'dome shaped'?
The squish area on the head is flat in both cases, the skim makes very little difference to the squish area, it gets marginally wider towards the valve seats as you machine into the sloped chamber wall, but very little changes..
138.8mm:
139.2mm:
you can see the flat squish area above the inlet valves in these pictures is almost identical..
