Description

<p>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.</p><p>This set is part of Hedman's ELITE line that uses stout 3/8" flanges, and thicker 14 gauge primary tubes. The heavy-duty construction of HEDMAN ELITE Hedders makes them ideal for high-performance engines, which produce higher exhaust temperatures.</p><p>ELITE models have a MATTE-SILVER ceramic finish that can withstand temperatures up to 1400 degrees F. The coating looks great, and keeps more heat in the tubes, resulting in faster exhaust speeds for improved scavenging, and reduced underhood temperatures.</p><p>These 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 D167-9 by C.A.R.B., making these headers 50-state legal on the 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.</p><p>Each set includes a pair of gaskets, header flange bolts and collector bolts. No collector gasket is needed.</p><p>Hedman Hedders is so confident in the quality of its headers that these headers are factory backed by a Limited Lifetime Warranty. The ceramic-metallic coating is covered by a 5-year factory warranty, in addition to Hedman's standard lifetime header warranty.</p>

Hedman Hedders, began as a one man shop in 1954. Bob Hedman, founder of Hedman Hedders, sold his highly sought after exhaust tubes to fellow racers on the salt flats of the Mojave Desert. But, what started out as a way to make a few bucks to pay for Bob's racing hobby, quickly turned into the premier header manufacturer for both the racing and street header marketplaces.\n\nOriginally designed for straightline drag racers, word spread quickly about Hedman's reputation for building headers that gave you the best boost in power for your dollar. It wasn't long before Hedman Hedders was the brand of choice among racing's elite engine builders, racers and race series. Familiar names like Don Garlits, Warren Johnson, Shirley Muldowney, Bob Chandler and his BIG FOOT Race Team, and the IROC series.\n\nHedman Hedders constantly reshapes itself to meet environmental requirements and incorporates computer technology to ensure that its products offer the best performance improvement.\n\nWhether you're a Pro or sportsman racer, Hedman Hedders builds your headers with one goal in mind, optimum performance. Even if you're not a racer, the lessons Hedman learns at the track and on the dyno, make it into every street header we design.
