I was not taying that opening up the chamber created quench, or at least I was not intending to. It was merely the only way I could think of to lower the compression to an acceptable level and still remain in a squeeze zone tight enough to create a quench effect(.035-.050 area) with a flat top piston with valve notches. I had not considered what nm9stheham had suggested. Using pistons and creating a squish along the sides and focusing on that area for the quench. I also didn't know of a piston that had that small of an amount of cc in the hole. The ones I saw were all around 20cc.
