I have been researching combustion chamber and piston design a little. I know now why pistons in conventional direct injected engines have bowls. Among other reasons, the bowl is designed to swirl the air as the piston ascends.

These pics are of an additional head I picked up. I have yet to pull the head off the test engine but the combustion chambers are the same. I will need to pull the head regardless and will study the piston tops then.

Really reaching out there, lol, it would be nice to build a Unit Injector System to run off the available cam lobes.
