Trick Flow® Billet Aluminum Valve Covers for GM LS
Trick Flow® billet valve covers are precision CNC machined in the USA from 6061-T6 aluminum and finished in durable black anodizing for a clean, high-end appearance. Designed with added clearance for shaft mount roller rocker arm systems, they are compatible with stock and aftermarket GM cylinder heads. An integrated oil drip rail helps reduce leaks while also aiding alignment during installation and removal. Driver and passenger side -12AN O-ring ports provide flexibility for crankcase ventilation systems, including catch cans and vacuum pump setups, while the included dyno-tested high-flow baffle system promotes efficient crankcase ventilation and minimizes oil vapor escaping through the PCV system. The baffle system is shipped uninstalled, allowing for additional valvetrain clearance or alternate PCV configurations when required. Each set includes a billet oil cap, stainless steel hardware, and uses factory-style gaskets for a secure, reliable seal. Optional universal coil mounting brackets fit GM LS and many aftermarket coils, or allow for remote mounting for a cleaner engine bay.

Trick Flow® GenX® 220 Cylinder Heads for GM LS2
Trick Flow GenX® 220 cylinder heads for GM 6.0L LS2 engines are the best value in GM LS performance. The cathedral port heads incorporate features of Trick Flow’s fully CNC-ported LS heads such as 13.5° valve angles, decreased valve shrouding, increased mid-lift airflow, relocated spark plugs, CNC-profiled combustion chambers with port-to-valve seat blending (bowl blending), improved rocker arm/ valve cover clearance, and rigid casting design in a more affordable “Fast As Cast” version that flows nearly as much air as Trick Flow’s competition ported heads. The special Fast As Cast® runner design duplicates the port shape and profile of fully CNC-ported runners, resulting in near-CNC-ported performance for the same price as regular cast cylinder heads. Trick Flow GenX 220 cylinder heads are emissions-legal under CARB E.O. #D-747 for 1997-present GM vehicles with 5.7L and 6.0L engines. They are available fully assembled or as bare castings. Sold individually.
