2008-2009 Pontiac G8 Cylinder Heads

For over thirty years Airflow Research has been defining technological leadership in cylinder head manufacturing and flow dynamics. This complete commitment to performance has enabled Airflow Research products to find themselves on the fastest race cars and the most powerful street machines in the country. As every engine builder will attest to, the secret to increasing horsepower and performance lies in the cylinder head, and Airflow Research’s cylinder heads outflow and out horsepower everything in their league.

Patriot Performance began its business with revolutionizing the CNC cylinder head market.  They are one of the largest suppliers of ported LS, Modular Ford, SBC, SBF, BBC, and other heads in the nation. The porting of performance heads has always been part of attaining maximum horsepower.

Patriot Performance designs their own CNC programs to port the chamber, bowl, and runners to attain maximum air and fuel flow. Slight alterations can affect that flow tremendously. Patriot's ported heads resemble works of art after they are machined.  Along with ported heads, they offer our Freedom series heads. With the introduction of our Freedom series, Patriot brought a revolution to the performance head market… performance and quality at a price everyone can afford. To optimize the flow in all of these heads, we have spent countless hours on proprietary valve seat designs. These designs have been developed to work along with their custom designed chambers and runners. All of Patriot's heads are built using the highest quality parts right here in the USA!
