These heads are equipped to accept factory style self-aligning rockers. The casting is manufactured of virgin A356 aluminum and heat treated to T6 spec for superior quality. An extra-thick 5/8" deck and Heli-coil threaded inserts offer improved durability. Performer LT1 cylinder heads are 50-state Street legal and accept factory centerbolt valve covers.
