SBC Universal Headers

The SBC Universal Headers from FLOWTECH are engineered for small-block Chevrolet engines seeking maximum exhaust scavenging and horsepower gains. These headers are designed for enthusiasts and builders who recognize that restrictive factory manifolds limit engine breathing and performance potential. Whether you're building a street machine, restoration project, or weekend track car, universal headers eliminate the thermal and flow penalties of cast-iron manifolds, allowing your SBC to achieve its intended power output.

FLOWTECH headers utilize mandrel-bent tube construction to maintain consistent internal diameter and minimize turbulence throughout the exhaust path, improving scavenging efficiency across the rpm range. The universal design accommodates common engine bay configurations without requiring custom fabrication, while the robust steel construction withstands the thermal and mechanical demands of sustained high-rpm operation. The stepped primary tube design ensures optimal velocity matching for both low-end torque and high-rpm power, a critical advantage over single-diameter alternatives that compromise across the power band.

These headers work across a wide range of small-block Chevrolet applications, from 283 to 400 cubic inch engines, making them ideal for hot rod builders, classic car restorers, and performance enthusiasts seeking bolt-on efficiency gains without engine removal. Installation requires standard hand tools and basic mechanical knowledge, with straightforward collector design for seamless integration into most exhaust systems. The 21.6 lb weight reflects quality steel construction rather than cost-cutting aluminum, ensuring durability for daily driving and competition use alike.
