FF3GTS Headers

The Sanderson FF3GTS header set is engineered for small block Ford 289-302 and 351W engines, specifically designed for 1964-73 Ford Mustangs. Its versatile design also makes it a suitable choice for a variety of other Ford applications, including the 1963-70 Ford Falcon, 1960-65 Ford Ranchero, Torino, and Mercury Cougar, as well as some truck applications. Constructed with 16-gauge primary and collector tubes and a 3/8″ thick flange, these headers offer durability. Sanderson's patented flange design eliminates the need for gaskets, ensuring a leak-free seal. The headers provide excellent spark plug and ground clearance, contributing to performance gains over stock exhaust manifolds and are compatible with GT40-P cylinder heads. Installation requires selecting the correct engine group (221-302 or 351W) and Ford transmission type (C4/C6, Manual, AOD, AOD-E, 4R70, or 4R75) during purchase. All necessary hardware for installation is included. Sanderson Headers are not emissions legal on pollution-controlled vehicles, and it is the purchaser's responsibility to verify local regulations. Wrapping the headers with thermal tape will void the manufacturer's limited 5-year warranty.
