World Products collaborated with leading racers to develop the Warhawk LS1 performance cylinder head line. These World Products Warhawk 15 degree LS1X cylinder heads are a significant improvement over factory LS1 cylinder heads. Warhawk cylinder heads are available with either 200cc or 220cc intake runners for the perfect combination of airflow volume and velocity. Warhawk heads have both the intake valve and the rocker arm studs canted 15 degrees to ensure perfect valvetrain geometry, even when longer-than-stock valves are used. World Products Warhawk heads also feature a raised valve cover rail to clear aftermarket rocker arms.
