Hedman Hedders is a name known for quality and performance at a fair price. Bolting on a set of these headers will improve both performance and efficiency. They are available for 1964-73 GTO, Tempest and LeMans in two versions and two finishes. The first finish is the standard painted version and then there's the polished, ceramic coated HTC version for long-lasting looks and performance. The full-length, four-tube headers feature 1-3/4" diameter, heavy-gauge tubes with 1/4"-thick port flanges and 3" diameter collectors that will work with either automatic or floor-mounted manual shifting transmissions. The second version is the shorty-design, which has the maximum ground clearance with 1-5/8" tubes going into a 2-1/2" collector and is for floor shift automatic transmission cars only.
