Would the quench area be the same for both ?

The best combustion chamber would be a sphere with the spark source in the center. The next best would be a dished (reverse dome) piston since the flame path is shorter and less chamber surface area is available to quench the flame front.
since we are applying pressure to the top of the piston to turn the crank,
wouldn't you want to use the entire piston top since that pressure is expressed as psi?
