I'd like your thoughts on which cylinder head is going to work best in this situation.
In the future, I'm going to build a turbo A14. I was lucky enough to pick up these

For a good price. They're unused, and have ceramic coated crowns and teflon coated skirts. E15eT pistons have the same comp height as the A14, but they have 10x the dish volume. This will enable me to run zero deck for good squish, but still have a nice low CR.
now the combustion chambers from this engine look like this

So considering people strive for nice small chambers on HiPo N/A motors to get good compression, what chamber configuration do you think would work best with these pistons?
I have a GX head, and H75 (40thou shaved) and numerous H89's. Considering the large surface area of the dish, would I be better to use a chamber that is open to mirror the piston?
