Build serious street power!
These Trick Flow GenX® 215 cathedral port cylinder heads for GM 5.7L LS1 engines are fully CNC-machined to significantly increase the performance of LS1-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.
Cylinder heads are available fully assembled or as bare castings
PRICES ARE FOR AN INDIVIDUAL HEAD. TRICK FLOW CYLINDER HEADS SOLD EACH.
