  • Trick Flow GenX® 215 cathedral port cylinder heads are fully CNC-machined to significantly increase the performance of 5.7L LS1 engines.

Top-of-the-line CNC Competition Ported runners have a premium high resolution surface finish for maximum flow and performance. 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.
