Coated Headers - GM Truck w/SBC

The Coated Headers for GM Truck w/SBC from HEDMAN are specifically designed exhaust manifolds for Small Block Chevy engines in General Motors light-duty trucks. These headers are engineered to replace the restrictive factory cast-iron manifolds, enhancing exhaust gas exit efficiency and improving overall engine performance. Ideal for classic restorations, work truck upgrades, or performance enhancements, these headers are essential for serious engine modifications.

HEDMAN's coated construction features tuned primary tube diameters and a protective ceramic or metallic coating that resists corrosion and thermal damage. This coating not only extends the headers' lifespan in harsh environments but also helps manage under-hood temperatures, ensuring the safety of engine bay components during prolonged use. The optimized tube length and diameter promote proper exhaust scavenging, which can lead to significant horsepower and torque gains across the RPM range without necessitating fuel system recalibration.

These headers are compatible with GM trucks equipped with Small Block Chevy engines and are most effective when paired with a suitable exhaust system and intake upgrades. Installation involves disconnecting the factory manifolds and fitting the new headers into existing mounting points, typically completed by experienced mechanics in 2 to 4 hours using standard hand tools. This combination of performance and ease of installation makes them a valuable addition for any truck enthusiast.
