66-77 Bronco 302W Header HTC Coated

The 66-77 Bronco 302W Header HTC Coated is a purpose-built exhaust manifold designed for first and second-generation Ford Bronco owners running Small Block Ford 302 engines who demand improved scavenging and heat management. Street-focused headers like this unit have become essential upgrades for vintage 4x4 enthusiasts looking to unlock horsepower while maintaining reliable, everyday drivability. Whether you're restoring a classic Bronco or maximizing performance on an existing build, proper header selection directly impacts combustion efficiency, throttle response, and underhood temperatures.

This header assembly features 1.5-inch primary tubes that merge into a 2.5-inch collector, geometry optimized for the 302 displacement and typical street-cruising RPM ranges where Small Block Fords produce peak torque. The HTC (High Temperature Ceramic) metallic coating reduces radiant heat transfer into the engine bay by up to 80 degrees Fahrenheit compared to bare steel, a critical advantage in compact vehicle spaces like the Bronco where underhood real estate is tight and engine temperatures run hot. Steel construction with ceramic thermal barrier technology ensures durability through thermal cycling, while the included gaskets and hardware simplify bolt-on installation—no custom fabrication required.

Bronco 302W engine swaps and restorations represent a significant portion of the classic 4x4 market, and this header is specifically engineered for that application across 1968–1977 model years. The pair configuration matches OEM manifold flange positioning, allowing direct bolt-on fitment without welding or extensive bracket modifications. Mechanics and weekend builders appreciate the complete gasket and fastener package, which eliminates the frustration of sourcing hard-to-find vintage hardware. Expect noticeable improvements in exhaust flow, cooler engine bay temperatures, and refined throttle character once installation is complete.
