Shop Hedman Headers Marken Performance 1-888-401-1362
Hedman Husler’s mid-length headers are engineered to maximize exhaust flow and ground clearance, delivering nearly the gains of a full length header without the associated ground clearance issues. Designed to fit 1964-1967 and 1968-1972 GM A-Bodies equipped with transplanted LS engines and T-56, 4L60E, 4L65E, or 4L80E transmissions, these headers are available with large 1 ¾-inch primaries and 3-inch collectors to complement everything from the basic street build to the heaviest breathing naturally aspirated or supercharged engines.
These headers are available in your choice of either an uncoated finish (Part# 45180 and 45540), silver HTC high-temp ceramic-metallic coating (Part# 45186 and 45546), or in Hedman Husler’s new Black Maxx black ceramic coating (Part# 45183 and 45543).
Mounting hardware, gaskets, O2 bungs and installation instructions are included with the headers. For a guaranteed fit, it is STRONGLY recommended that the companion Muscle Rods LS swap conversion mount kits, which were designed at the same time as the headers, be used during installation (mount kits sold separately). This ensures that the engine is properly located in the engine bay, and that the factory recommended 3 to 5 degree pinion angle is maintained.
