Ford Racing GT-40 Cylinder Heads
With Ford Racing’s GT-40X “Turbo Swirl” heads you can bolt on up to 65 horsepower. For use on 289/302/351W engines, these heads flow better than the original GT-40 heads and are compatible with factory intake and exhaust manifolds, headers, bolt-on style rocker arms and valve covers. Heads are completely assembled with 1.94” intake and 1.54” exhaust valves, with a choice of 58cc or 64cc combustion chambers.
