Mine picked up going from 34* to 32*, it has .034" quench. In one of Ryan's posts a couple years ago he posted some dyno results on one of his engines. The engine had good quench and small chamber heads with dual quench pads. IIRC it made the most power at 28*.




That was my thinking too, These heads have double quench pads, I may knock it down to 26 to start with.
