Sanderson Headers BNH1-P Buick V8 Nailhead Shorty

The BNH1-P is one of our latest designs in a series of headers for "nostalgia" engines. The letters "BNH" stand for "Buick Nailhead", the veneragle Buick V8 engine that powered numerous dragsters, lakesters, and hot rods in the sixties and seventies. 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 center of the engine.  A build-up series by Doc Frohmader in Street Rodder Magazine has sparked a renewed interest in the might 401/425 engines.

Comes with all hardware necessary for installation.

   2. Sanderson Headers are NOT emissions legal on pollution-controlled motor vehicles. It is the purchaser's responsibility to verify local regulations for compliance.
   3. Wrapping your Sanderson Headers with ANY thermal tape voids your header warranty. The best thermal protection for your headers is our Aluminized Ceramic Coating that is available for every Sanderson Header.
