67-81 Sb Camaro/Chevy II

The Hedman 67-81 Small Block Chevy Headers for Camaro and Chevy II deliver proven performance gains for classic F-Body and X-Body muscle cars. This pair of street headers features 1.625-inch primary tubes that merge into a 3-inch collector, engineered to maximize exhaust scavenging and unlock horsepower without sacrificing streetability. Constructed from steel with metallic ceramic coating, these headers resist corrosion and heat while maintaining the durability required for daily driving and weekend cruising.

The 1.625-inch primary diameter is optimized for Small Block Chevy displacement and RPM range, promoting efficient low-to-mid-range torque delivery typical of 1967–1981 vehicles. The 3-inch collector provides transition area that balances back-pressure for street engines while preparing exhaust flow for typical single or dual exhaust systems. Metallic ceramic coating protects against oxidation and reflects radiant heat away from the engine bay, reducing underhood temperatures and extending component life. Gaskets and hardware are included, streamlining installation and ensuring a complete package out of the box.

These headers are purpose-built for second-generation Camaros (1967–1981) and Chevy II/Nova models using Small Block Chevy engines. Whether you're restoring a classic, upgrading an existing street machine, or building a period-correct performance platform, this header set addresses the flow limitations of factory cast-iron manifolds. The street-tuned design balances power gains with real-world compatibility, avoiding the extreme port sizing and tuning parameters that restrict drivability on original carburetor or early fuel-injection systems.

Hedman Headers remain a standard choice in the classic Chevy performance market, recognized for consistent quality and fitment across GM F-Body and X-Body platforms. The combination of proven design, included gasket set, and ceramic protection makes this a straightforward upgrade path for builders prioritizing reliability and value.
