Total Engine Airflow Trick Flow Cylinder Heads

Trick Flow's latest offering for the LS-1,2,and 6 engines. This head has been designed on a 13.5 degree valve angle, and uses stock length LS-1 valves and valvetrain components for use with hydraulic roller cams. The flatter valve angle allows for more piston to valve clearance with a 2.040" valve than a stock 5.7 head with a 2.0" valve. In order to maximize midlift airflow and improve combustion the spark plug has also been rotated away from the intake valve seat which eliminates the plug boss and coupled with the 13.5 degree angle makes this head flow more through the midlift than everything else available. Trickflow has built this head with a .600" thick deck to provide ample deck thickness for head gasket integrity without compromising cooling ability. We currently offer port designs to fit 3.9, 4.00, and 4.125" applications. Note: A roller tipped rocker and .100" longer than stock pushrod is required with these heads.
