70-81 Sb Camaro Header

The HEDMAN 70-81 Small Block Camaro header (Part 65104) is purpose-built for second-generation Camaro owners seeking genuine performance gains and improved exhaust flow characteristics. Whether you're running a stock 350 or a modified small block, this header replaces the restrictive factory cast-iron manifold with a properly designed tubular exhaust solution that reduces backpressure and frees up horsepower. These headers are essential for any street or strip Camaro that demands responsive throttle feel and efficient scavenging across the RPM range.

HEDMAN headers are engineered with mandrel-bent primaries that maintain optimal tube diameter through every curve, preventing the dead spots and turbulence created by crushed or welded factory manifolds. The tubing diameter and runner length are sized to match small block Chevrolet port characteristics, delivering peak scavenging efficiency without sacrificing low-end torque. Weighing 33.33 lbs, this header offers substantial weight savings compared to cast iron while maintaining rigidity under sustained heat cycles. The construction process ensures consistent collector alignment and leak-free flanged connections at the cylinder head.

These headers are purpose-designed for the 1970–1981 Camaro chassis and work with both carbureted and fuel-injected small block conversions. Installation requires basic hand tools and mechanical aptitude; the header bolts directly to factory mounting points, though secondary brackets may need repositioning depending on your accessory configuration. Pair this header with a quality exhaust system—mandrel-bent cat-back piping amplifies the benefits—and expect noticeable responsiveness gains and a more aggressive exhaust note that confirms the improved flow dynamics.
