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!
