Hedman Hedders has been manufacturing quality headers in the USA since 1954, and they've been manufacturing Ford Mustang headers for nearly as long as Mustangs have been on the road. Each set uses mild steel, smooth flowing, CNC mandrel bent tubes, that are hand-welded to ensure each pair is identical to the next. Hedman's unique, gasketless ball and socket collector design allows your exhaust system to bolt up to these 351W engine swap headers, even if it is not perfectly aligned with the header collectors.

These uncoated mild steel, LONG-TUBE headers are designed specifically for swapping a 351W engine into (non-factory 351W equipped) 1964-73 Ford Mustang, Falcon, or '66-73 Ranchero, Torino. The engine must be centered between the framerails. These headers fit both automatic and manual transmissions, but won't work with 4 speed top-loader tranmissions, and clutch and shift linkage may be required. The smooth 1-5/8 in., oval port tube design tucks in tight to clear shock towers, and provide excellent flow to let your 351W engine breathe better, and produce excellent low-end torque and horsepower.

These headers are uncoated, and ship from the factory with a temporary black paint that will burn off when submitted to normal operating temperatures. For protection against the element and lower underhood temperatures, these headers are also available with a silver or black ceramic-metallic finish.

Each set includes a pair of gaskets, header flange bolts and collector bolts. No collector gasket is needed.
