58-64 Sb Chevy Passenger

The 58-64 SB Chevy Passenger headers from HEDMAN are designed for classic small-block Chevrolet engines, specifically for street and restoration applications. These headers replace restrictive factory cast-iron manifolds, enhancing horsepower and improving engine breathing for 1958–1964 models.

Engineered with mandrel-bent, stepped primary tubes, these headers optimize exhaust gas velocity and scavenging action across the RPM range. The tuned collector design reduces backpressure while maintaining adequate velocity for effective cylinder-to-cylinder scavenging. Constructed from heavy-gauge mild steel, they are available in either a durable ceramic or polished finish, ensuring longevity under high-temperature conditions.

Restorers and hot-rod builders appreciate HEDMAN headers for their authentic design and bolt-on compatibility with original mounting points. These headers not only improve performance but also fit unobtrusively in the tight engine bays typical of 1958–1964 Chevrolet chassis, making them an ideal choice for enthusiasts looking to enhance their vehicles.
