Yes, that dish shape creates dual quench areas when used with a carefully machined, 68 and later head. Definitely a custom machinning job.
It is a challenge to get the piston up that high in the chamber, compression is a solid 13 to 1.
Here is the dish lay-out in case you want to give one of these combos a try.
