Hedman Hedders: GM A-Body Headers for ’64-’67 Big-Block Chevy

Offering excellent ground clearance and awesome horsepower, big-block GM A-Body headers from Hedman Hedders are the only mid-length headers for 1964–1967 Chevrolet Chevelle, El Camino, and GTO. The advantage these headers have is that they don’t hang below the frame rails like the long-tube headers for those vehicles, sparing them from road hazards like bumps and driveways. They fit automatic transmission–equipped models and are compatible with A/C and power steering. The shorter, mid-length headers provide superb ground clearance—especially for lowered, pro-touring style builds—yet offer superior performance over short-tube headers or factory manifolds.

Hedman makes these headers in the USA from mandrel-bent, 1-3/4” primary tubes, with 3/8” header flanges and a 3” ball/socket-style gasket-free collector. The larger, free-flowing tubes improve exhaust scavenging to produce excellent horsepower and throttle response from your Rat motor. Hedman backs header construction with a lifetime warranty, and all factory-applied finishes are warrantied for five full years. Available finishes include HTC polished silver ceramic (68666), Black Maxx ceramic-metallic (68663), or uncoated (68660).
