The outside edge of the chamber and piston already create a
slight squish area. However, it looks very narrow. I don't know the piston-head clearance yet; I haven't yet disassembled the engine. The simplest thing I have found that I can do is get a thinner head gasket; losing half-thickness (0.6mm) will raise my CR from 9:1 to 10:1 and bring the piston closer to the chamber for better squish.
