Mustang 351w Conv.F/Leng Header

Hedman's Standard-duty, Uncoated Hedders are manufactured using 18 gauge, mandrel bent primary tubes and 1/4" flanges. Each set uses mild steel, smooth flowing, CNC mandrel bent tubes, that are hand-welded. Hedman's unique, gasketless ball and socket collector design allows your exhaust system to bolt up even if it is not perfectly aligned. 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 frame rails. These headers fit both automatic and manual transmissions, but won't work with 4 speed top-loader transmissions, 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. 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. Factory backed by a Limited Lifetime Warranty.
