WARHAWK LS1X 15°

LS GEN III / IV CHEVROLET

ALUMINUM CYLINDER HEADS

Designed primarily for street applications, Warhawk® LS1X 15° heads represent significant improvements over factory heads, and are second to none when compared to other aftermarket versions. Designed with 235cc intake runners, it enables engine builders to get the optimum balance of air flow and velocity. Another key improvement of the Warhawk® is that both the valve centerline and rocker arm attachment are parallel at 15° to assure correct geometry, even when longer-than-stock valves are used. Enjoy significant “out of the box power increases with Warhawk LS1X heads!
