The BNH1 is one of our header designs for “nostalgia” engines. The letters “BNH” stand for “Buick Nailhead”, the venerable Buick V8 engine that powered numerous dragsters, lakesters, and hot rods in the sixties and seventies. A build-up series some time ago by Doc Frohmader in Street Rodder Magazine has sparked a renewed interest in the mighty 364, 401, and 425 engines.
The BNH1 header fits all street rod chassis, pickups, and customs without a cross member under the center of the engine, or steering interference just behind the center of the engine.
Comes with all hardware necessary for installation.

Our Ceramic Coating is recommended for every vehicle application and is the default finish selection choice above. To meet high standards of quality, We apply a multi-layer inside and outside aluminized ceramic coating in-house and then polish the coating to a high luster. This aerospace and military-grade technology adds excellent protection to your headers while offering the benefit of thermal control in your engine bay. It also improves cylinder scavenging of exhaust gases and increases the longevity of your header investment.
