65-75 Olds 442 Headers 400-455

The 65-75 Olds 442 Headers 400-455 by HOOKER are an essential upgrade for automotive enthusiasts looking to enhance the performance of their first-generation Oldsmobile 442. Designed specifically for the 400 and 455 cubic inch V8 engines, these headers are perfect for both restoration projects and performance builds. They help maximize exhaust flow, which is crucial for unlocking the engine's full potential.

Constructed from heavy-gauge steel, these tube headers feature precision-mandrel bending to maintain consistent diameter throughout each primary tube. This design is critical for effective exhaust gas scavenging across all RPM ranges. The headers also include cast nodular iron flanges, which provide superior strength at the cylinder head interface, reducing the risk of cracking and warping.

Restoration shops and performance builders appreciate these headers for their durability and performance benefits. They are compatible with 1965–1975 442 models equipped with either the 400 or 455 engines, making them a versatile choice for anyone looking to enhance their muscle car's performance.
