Hedman Hedders has been manufacturing quality headers in the USA since 1954, and they've been manufacturing Ford truck headers decades. 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 Ford 351M/400 headers, even if it is not perfectly aligned with the header collectors.
These uncoated, LONG-TUBE, fenderwell-exit headers fit 1977-79 Ford 1/2, 3/4 and 1 ton, 4WD Trucks and Broncos with a 351m or 400 engine. The long, smooth-flowing 1-5/8 in. tube design provides great exhaust flow to let your Ford truck or Bronco's 351M of 400 engine breathe easy, and produce loads of torque. They fit both automatic and manual transmission vehicles.
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.
Hedman Hedders is so confident in the quality of its headers that these headers are factory backed by a Limited Lifetime Warranty.
