Patriot Performance Ford 4.6 / 5.4L SOHC (PI) Stage III Head Bare W/O Cam V8.
Stage III SOHC cylinder heads from Patriot Performance are designed to add a 40 to 50 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 1.84 / 1.45 valve job, and then hand blend. Ideal for street and strip applications, these CNC-ported heads flow over 225 cfm and can handle blown or nitrous setups. These are perfect addition to your 2 valve Mustang or other modular build. Because of the larger intake valve, we do not suggest for use on stock bore applications.
Sold as Pair. When using these on non-PI motors, use PI intake. Technical Specs: - Combustion Chamber: 46cc
