For maximum performance form an LS-series engine, World’s WARHAWK 12 degree heads are the answer. As a result of superior port esign and exclusive RightCast technology, the WARHAWK 12 degree has 285cc intake and 106cc exhaust runners that flow incredible numbers. If even more flow is desired, World offers CNC-ported versions of this head that boast 296cc intake and 110cc exhaust runners. The ports were designed by noted LS specialist Kuntz & Co. and they’re dyno-proven to crank out the power! Available as bare castings or in race-ready assemblies that have a multi-angle intake valve job and radiused exhaust, are equipped with stainless Manley 2.200” diameter intake and 1.600” exhaust valves, high performance springs and Manley chrome moly retainers. Compatible with stock LS7 rocker arms and integral stands. The heads can accommodate 1.625 diameter valve springs and valves with an overall length of 5.500”. An important feature of the WARHAWK 12 degree 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.
