Hedman Hedders has been manufacturing quality headers in the USA since 1954, and they've been manufacturing long and MID-LENGTH tube headers for Chevy passenger cars for 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 Small Block Chevy exhaust system to bolt up, even if it is not perfectly aligned with the header collectors.
These LONG-TUBE headers fit a variety of 1978-1987 GM A-Body and G-Body vehicles, including Buick Regal, Chevy Chevelle, El Camino, Monte Carlo, and Pontiac Grand Prix models fitted with a SB Chevy (Gen 1) engine. The smooth 1-1/2 in. tube design provides ample exhaust flow to let your 283-400 SB Chevy engine breathe easy, and produce maximum horsepower and torque.
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.

Hedders come with all the gaskets and hardware you need, plus instructions. All of Hedman’s Street Hedders are warranted for life, while Husler Hedders for racing have a 3-year limited warranty. Hedman also makes mufflers, exhaust tips, tubing, and other exhaust parts to those same high standards of performance and quality.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 Bobs racing hobby, quickly turned into the premier header manufacturer for both the racing and street header marketplaces.
Originally designed for straightline drag racers, word spread quickly about Hedmans reputation for building headers that gave you the best boost in power for your dollar. It wasnt long before Hedman Hedders was the brand of choice among racings 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.
Hedman Hedders constantly reshapes itself to meet environmental requirements and incorporates computer technology to ensure that its products offer the best performance improvement.
Whether youre a Pro or sportsman racer, Hedman Hedders builds your headers with one goal in mind, optimum performance. Even if youre not a racer, the lessons Hedman learns at the track and on the dyno, make it into every street header we design.
