When the engineers at GM developed the LS series of engines, they provided enthusiasts with the most technologically advanced small block Chevy ever. Now, Trick Flow has raised the bar of serious horsepower by developing new LS cylinder heads that significantly increase the performance of late model GM musclecars. During the development stage of the Trick Flow GenX Street/Strip CNC-ported cylinder heads, Trick Flow engineers determined that the valve angles needed to change from 15º to 13.5º to decrease valve shrouding, increase mid-lift airflow, and improve rocker arm-to-valve cover clearance. Testing also proved that relocating the spark plugs in the combustion chambers further enhanced mid-lift airflow and increased the rigidity of the casting for extreme horsepower applications. Furthermore, additional material was added to the rocker arm mounting points for high-rpm valvetrain stability.

Assembled heads come equipped with 1.300" dual valve springs (for hydraulic roller camshafts up to 0.600 in. of valve lift),Viton® fluoroelastomer canister-style valve seals, 7º machined steel valve locks, and 7º titanium retainers.

Tech Note:

All TFS LS Cylinder Heads require the use of roller tip rocker arms! Any roller tip rocker arm for LS1/LS6 applications will fit the TFS heads.
