For maximum performance form an LS-series engine, World’s WARHAWK 12° heads are the answer. As a result of superior port design and exclusive RightCast technology, the WARHAWK 12° has 285cc intake and 106cc exhaust runners that flow incredible numbers. An important feature of the WARHAWK 12° head is that it comes with two extra bold holes per cylinder (same as WARHAWK LS7X blocks) to provide extra sealing power for power adder combinations with higher combustion pressures.
