More Power. Increase the horsepower and torque output of your push rod 5.0L engine with the Ford Racing Turbo-Swirl GT40X Aluminum Head. These GT-40X heads feature a 64CC Combustion Chamber to greatly improve the airflow over the original GT-40 design allowing you to bolt on 65 more horsepower.

Improved Air Flow. These Ford Racing GT-40X heads have an intake port volume of 178cc allowing for an intake flow of approximately 240 cfm at .550" lift (at 28" of H20) and an exhaust port volume of 62cc allowing for an exhaust flow of approximately 170 cfm at .500" lift (at 28" of H20). Machined for 1.94" Intake and 1.54" exhaust valve diameters.

Lightweight. Made from high quality original equipment style 356-T6 aluminum castings, each head weighs in at only 22 lbs. that is 25 lbs. lighter than the original cast iron GT-40 head, that is a weight savings of 50 lbs.

Fully Assembled. Leak tested prior to assembly, each Ford Racing Turbo-Swirl GT40X Aluminum Head comes fully assembled with M-6507-J302 intake valves, M-6505-G302 exhaust valves, and M-6513-A50 valve springs. As an added bonus the valve springs are compatible with all Ford Racing roller camshafts.

Installation Notes. Ford racing "X" heads are designed to use either GT-40 or aftermarket performance intake manifolds, M9439A50 intake gasket, and AGSF-32C spark plugs. Designed for bolt-down rocker arms part number M-6564-B351 for a 1.6 ratio or use part number M-6564-A50 for a 1.7 ratio.

Application. The Ford Racing Turbo-Swirl GT40X Aluminum Head is designed to be a direct bolt-on for the 1982-1985 and 1987-1995 5.0L Windsor-style V8 engines. It will not fit 1986 5.0L with flat-top pistons unless pistons are notched for valve relief.

Technical Note. Be sure to check your intake manifold for port match, because not all intakes are compatible due to the tall high-flow ports.
