The 66-77 Sb Charger/Coronet headers by Hedman are designed for classic Dodge muscle car builds, specifically for 1966 through 1977 B-body Chargers and Coronets. These headers are engineered to replace restrictive factory cast-iron exhaust manifolds, enhancing horsepower and torque across the RPM range. They are an excellent choice for both restoring original vehicles and building modern restomods.
Constructed from mandrel-bent tubing with a precision-welded collector design, these headers optimize exhaust flow by reducing gas velocity turbulence and back-pressure. The stepped tube design accommodates varying cylinder performance characteristics, ensuring that each runner effectively maximizes flow for its respective cylinder head. This engineering minimizes heat soak in the engine bay while maintaining essential ground clearance.
Hedman headers are favored by mechanics and restorers for their bolt-in compatibility with original motor mounts and frame points, requiring no cutting or welding for installation. They are designed to work seamlessly with both carbureted and fuel-injected small-block applications, making them a versatile option for enthusiasts. Whether you're looking to enhance performance or maintain authenticity, these headers deliver reliable results.
