Offering excellent ground clearance and awesome horsepower, big-block GM A-Body headers from Hedman Hedders<\/a> are the only mid-length headers for 1964\u20131967 Chevrolet Chevelle, El Camino, and GTO. The advantage these headers have is that they don\u2019t 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\u2013equipped models and are compatible with A\/C and power steering. The shorter, mid-length headers provide superb ground clearance\u2014especially for lowered, pro-touring style builds\u2014yet offer superior performance over short-tube headers or factory manifolds.<\/p>\n

Hedman<\/a> makes these headers in the USA from mandrel-bent, 1-3\/4\u201d primary tubes, with 3\/8\u201d header flanges and a 3\u201d 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<\/a> 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).<\/p>\n
