I'm no engine guy so I'll tell you more than I know. I was under the impression that the quench area promoted turbulence in the cylinder on the compression stroke and the turbulence was beneficial to the combustion process... i.e., more complete burn and more resistance to detonation. I have read a couple of articles on how close the piston has to come to the head for the quench concept to be effective, but I seem to recall that the spacing should be less than 0.040" or so. I think you can order custom thickness gaskets from Cometic, but I would wonder if going from 0.064" to 0.050" would be worth the trouble.

Good luck
