Shorty Headers - 68-77 Olds 260-403

The HEDMAN Shorty Headers for 68–77 Oldsmobile 260–403 V8 engines deliver a practical, bolt-on solution for improved exhaust flow without requiring major engine bay modifications. These block-hugger headers fit tight against the engine block while clearing factory components, making them the go-to choice for street applications, restorations, and performance builds where full-length headers cannot be accommodated due to space constraints or accessory conflicts.

Constructed from steel and finished in durable black paint, the headers feature 1.75-inch primary tubes that optimize scavenging for mid-range torque and drivability, merging into a 3-inch collector that transitions to your existing exhaust system. The pair includes all necessary gaskets and hardware, eliminating the need for separate purchasing. This complete-package approach reduces installation time and ensures proper fitment. The 19.46-pound weight reflects solid steel construction designed to withstand heat cycling over years of use without warping or thermal cracking.

These shorty headers are ideal for Oldsmobile owners modernizing 260, 307, 350, and 403 cubic-inch V8 engines—whether building a street machine, restoring a classic, or upgrading a daily driver. The block-hugger design appeals to builders working with tight engine compartments, vintage air conditioning systems, or power steering installations where traditional full-length headers create clearance headaches. Dyno data consistently shows modest gains in mid-range horsepower and torque compared to stock manifolds, with real-world benefits in throttle response and overall drivability.
