What I mean DD is that if you have 2 or 3 or more different heads with different volume chambers then the compression won't be dictated by the dish on the piston regardless of head choice. It will be a combination of both the dish of the piston and the relevant chamber of the head. If you had an A15 with standard dished pistons that had a H89 then bolted on a H75 you would have an increased volume of compression space giving you lower compression.

Unless the open chamber head and closed chamber head have exactly the same CC then I am wrong.
