These Trick Flow GenX® 225 cathedral port cylinder heads for GM 6.0L LS2 engines are fully CNC-machined to significantly increase the performance of LS2-powered cars and trucks. Trick Flow engineers altered the valve angles from 15° to 13.5° to decrease valve shrouding, increase mid-lift airflow, and improve rocker arm-to-valve cover clearance. Material was added at the rocker arm mounting points to increase high-rpm valvetrain stability. The spark plugs were relocated in the CNC-profiled combustion chambers to enhance mid-lift airflow and increase the rigidity of the casting for extreme horsepower applications. Top-of-the-line CNC Competition Ported runners have a premium high resolution surface finish for maximum flow and performance.

Trick Flow GenX 225 cylinder heads are emissions-legal under CARB E.O. #D-747 for 1997-present GM vehicles with 4.8L, 5.3L, 5.7L, and 6.0L engines. They are available fully assembled or as bare castings. Sold individually.
