Coated Headers - SBC

The Patriot Exhaust Coated Headers for Small Block Chevy (SBC) deliver serious thermal management and durability for classic muscle car builds. These full-length headers feature a 1.625-inch primary tube diameter that flows into a 3-inch collector, optimized to match the displacement and RPM characteristics of small block Chevrolet engines across GM A-Body, B-Body, F-Body, and X-Body platforms from 1964 through 1989. The metallic ceramic coating provides both heat rejection and corrosion resistance in high-temperature exhaust environments, critical for vintage restoration and performance applications where traditional painted headers fail prematurely.

Constructed from steel with a durable ceramic coating, these headers reduce underhood temperatures significantly compared to original cast-iron manifolds while improving scavenging efficiency. The 1.625-inch primary diameter is sized to balance exhaust velocity across the RPM range typical of street and mild performance engines, avoiding the over-sizing that creates dead spots at lower engine speeds. The 3-inch collector exit provides a smooth transition to your exhaust system and allows for modern muffler and resonator fitment. This pair includes all necessary gaskets and mounting hardware, eliminating the need for separate purchases.

These headers are purpose-built for restomod enthusiasts, bracket racers, and street machine builders working with classic Chevrolets. Whether you're upgrading a numbers-matching 327, rebuilding a 350, or installing a stroker engine, properly sized headers are essential for maximizing both power output and engine longevity. The ceramic coating resists thermal fatigue and oxidation better than standard steel, extending service life even in show cars that see regular driving. Installation requires basic hand tools and fits within stock engine bay dimensions on all compatible A/B/F/X-Body platforms.
