Stock 1979 360 with Speedmaster head question

lots of threads on quench do a search
you have quench which is two cold surfaces (piston and head) with not enough fuel between to burn/ ping/ detonate
then you have "squish" which forces the gas to jet out into the chamber and have lots of motion which quickens burn
you want the chamber at tdc to be equal distences from the plug for a good flame front
what you do not want is a 440 chamber with the plug way over on one side (or early sbc)
perhaps someone will repost KBs Chief Engineer John Erbs write up on "quench" but he's talking about squish
