Stage II SOHC cylinder heads from Patriot Performance are designed to add a 35 to 40 rear wheel horsepower gain over stock PI heads. We begin with OEM Ford castings, then CNC port using our custom designed program, install bronze guides, perform our 5 angle 1.78" / 1.45" valve job, and then hand blend. Ideal for street and strip applications, these CNC-ported heads flow over 215cfm and can handle blown or nitrous setups. These are perfect addition to your 2 valve mustang or other modular build. Sold as Pair.
When using these on non-PI motors, use PI intake
