	I think your the closest John, as I understand it, detonation is caused by
two flame fronts colliding in the combustion chamber.  When you have a
flatter wider combustion chamber the chances of two flame fronts
propagating is increased.  The reason they are called Quench chambers is
because they quench the flame front therefore reducing the possibility of a
collision.  You are corrected the Quenching action leave more unburnt
hydrocarbons (dirty). Some judicious messaging of a quench chamber can get
you a pretty nice compromise.  There are also functions related to the
valve head size, intake swirl pattern, bore diameter and many more engine
parameters that effect useable CR.  Cam duration and overlap are two more, 
normally that functions works like this: more duration or more overlap =
use more compression.

Anyone else with thoughts on this
