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 Big Block Ford 385 headers, even if it is not perfectly aligned with the header collectors.
These HTC Coated, LONG-TUBE headers fit 1974-79 Ford 1/2, 3/4 and 1 ton, 2WD Trucks with a 429-460 engine. These headers have been successfully tested and assigned E.O. number D167-27 by C.A.R.B., making these headers 50-state legal on emissions-controlled 1975-1979 models without A.I.R. System. The long, smooth-flowing 1-3/4 in. tube design provides excellent exhaust flow to let your F-Series Ford truck's factory Big Block engine breathe easy, and produce loads of horsepower and torque. They fit manual and auto transmissions, but will not install on Camper Special or front swaybar equipped models.
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. These headers have a high temperature, POLISHED-SILVER ceramic finish that resists corrosion, and can withstand temperatures up to 1400 degree F. This finish is covered by a 5 year factory warranty, in addition to Hedman's standard lifetime header warranty.
