9 to 1 Piston for EQ 62cc Head

I didn't explain that right , i have used the 232 pistons for the X and J heads in the past , they have the bump for the open chamber/ dead ..... wasted space that the step takes care of and forces the mixture over to the combustion chamber to be reacted .
I'm wanting to switch to the EQ Double Quench Head for more efficient chambers and better port runners, but need to keep 9 to 1 and hold that tight quench for efficient burn.
so i guess i need a heck of a dish to get back to 9 to 1 , sounds like 600.00 custom pistons ??
