I would use the 711 gasket. When you get into this quench topics then it becomes more of a Stock Eliminator get every last HP issue rather than a good running 302 for the street. Don't worry about what everyone thinks, I've been in this hobby long enough to know that you will get 100 different answers from 100 different people. We get about 360-380 out of a stock rebuild on a pedigree 302 on pump gas. We can step it up from that if requested.
