| − | Consider this: These heads have 170cc intake runners. As such, they will do a very good job on a 355 small block Chevy motor when used as a daily driver with a flat-top or dished piston. If a builder has high static compression ratio in mind for the build, he would be silly to use the small runner heads with domed pistons to make high-rpm horsepower because the heads will stall sooner than larger runner heads . He'd naturally choose a different head that would flow more CFM. Therefore, I see no use for domed pistons to be used with L31 heads. An excellent 9.60:1 static compression ratio 355 street motor that will operate on pump gas can be built using a | + | Consider this: These heads have 170cc intake runners.
