Featuring valve pocket designs that allow maximum flow around valve, also allowing oversized valves and high lift cams to be utilized. Piston crown shapes designed to promote maximum intake charge efficiency thru scavenging mixture “cross flow” during intake and exhaust valve overlap. More fuel and air equals more horsepower!
