Ford Street Rod Headers

The Hedman Ford Street Rod Headers (model 88420) are purpose-built exhaust manifolds designed for classic Ford street rods and hot rods, aiming to maximize scavenging efficiency and enhance engine performance. These headers are ideal for builders and restoration enthusiasts looking to improve horsepower while preserving the traditional hot rod aesthetic.

Engineered with stepped primary tubes, these headers feature larger diameter passages that progressively reduce restriction as exhaust gases flow from the cylinder head to the collector. This design enhances scavenging at low RPM while maintaining velocity at higher speeds, resulting in a broad powerband improvement. The header tubes are mandrel-bent to eliminate turbulence-inducing kinks, and the collector is sized to optimize exhaust gas velocity for consistent back-pressure.

These Hedman headers are best suited for carbureted or early fuel-injected Ford engines, typically found in small-block or big-block platforms. They provide significant weight savings and improved exhaust flow, directly translating to enhanced drivability. Installation requires basic automotive mechanical skills, making them accessible for enthusiasts looking to upgrade their street rod.
