Gain Up to 40 HP. Patriot Performance designs their Stage II SOHC heads to add from 35 to 40 more horsepower to your rear wheels, turning even the tamest Mustang into a track-day terror.

Street and Strip. These free-flowing CNC-ported heads deliver over 215 cfm and can handle blown and nitrous applications. They're a great choice for high-powered Ponies that stretch their legs on both the street and the strip.

Made to Perform. Patriot Performance Stage II 1020 Superflow Bench 3.552 Bore Heads for PI Romeo blocks feature 46cc combustion chambers with 180cc intake runners and 67cc exhaust runners. 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 II Specs. The Stage II heads are designed for airflow with their 1.78" intake valves flowing 64 CFM at .100 lift and 218 CFM at the full .600 lift and their 1.452" exhaust flowing 52CFM at .100 lift and 193 CFM at .600.

Fully Assembled. Patriot Performance Stage II 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 II 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.
