Hedman Longtube Headers 1-5/8" Uncoated 283-400 S/B Manual Chevy/GMC Truck 67-87

Improve your 1967-1987 2WD or 4WD Chevy C10’s exhaust flow with a pair of Hedman Uncoated 1-5/8” Longtube Headers! These mild steel headers are hand-welded in the USA from CNC mandrel-bent tubing with a 1-5/8” diameter for excellent airflow. They use a unique ball-and-socket collector design that eliminates the need for a gasket, allowing your existing exhaust system to bolt right on even if it’s slightly out of alignment with the new collectors. These headers fit the factory stock profile heads and arrive uncoated (aside from temporary black paint that burns off under normal operating temperatures).
