Gain Up to 50 HP. Patriot Performance designs their Stage III SOHC heads to add from 40 to 50 more horsepower to your rear wheels, unleashing the absolute maximum potential from your Mustang's engine. These heads are the basis for a take-no-prisoners engine build.

Street and Strip. These free-flowing CNC-ported heads deliver over 225 cfm and can handle blown and nitrous applications. They're a great choice for the ultimate strip 'Stang. Because of the large intake valve, we do not suggest that they be used on standard bore applications.

Made to Perform. Patriot Performance Stage III 1020 Superflow Bench 3.552 Bore Heads for PI Romeo blocks feature 46cc combustion chambers with 180cc intake runners and 67cc exhaust runners. They come complete with Patriot's Custom Stainless Steel Valves and .600" Lift Springs with titanium retainers. Every last detail of a high performance racing head is taken into account at Patriot including a 5 angle valve job and 5-axis CNC porting.

Stage III Specs. The Stage III heads are designed for forced-induction airflow with their 1.84" intake valves flowing 68 CFM at .100 lift and 226 CFM at the full .600 lift and their 1.453" exhaust valves flowing 53CFM at .100 lift and 201 CFM at .600.

Fully Assembled. Patriot Performance Stage III heads complete with Patriot's Custom Stainless Steel Valves and .600" Lift Springs with titanium retainers. Rockers, lifters, and cams sold separately.

Application. The Patriot Performance Stage III heads fit all PI Romeo Block 4.6L/5.4L SOHC 2V Ford Motors, such as the 2001-2004 Mustang GT. Will not fit Windsor blocks.

Technical Notes. Patriot Performance Heads are built to order by Patriot Performance for our customers. Because of this there can be a 4 to 6 week lead time on orders. May not be legal in emissions controlled states. For help identifying your block, Romeo Blocks have 11 bolt valve covers, Windsor Blocks have 13 bolt valve covers. These heads do not fit Windsor Blocks.
