    DART Pro 1 LS3 15 Degree Cylinder Heads | 280cc 68cc Chamber

    "With a stock valve in the head and no porting other than a bowl blend these flow just over 370 cfm on the intake side at .800-inch lift, but it’s the exhaust side that’s the killer – these castings have 252 cfm of exhaust flow at .800-inch lift! – Richard Maskin, Dart Machinery"
