S-10 V-8 Headers

The Hedman S-10 V-8 Headers are street-performance exhaust manifolds engineered for small block Chevy applications in GM compact SUVs and trucks from 1982–2000. This pair features 1.5-inch primary tubes that merge into a 2.5-inch collector, optimizing the scavenging process for improved exhaust flow and engine efficiency. Constructed from steel with a durable black paint finish, these headers are designed to bolt onto your existing engine bay while accommodating stock or mildly modified engine configurations.

The 1.5-inch primary diameter is sized to match the typical displacement and RPM range of small block Chevy engines, minimizing backpressure while maintaining scavenging velocity across the operating band. The stepped 2.5-inch collector consolidates the four primary tubes into a single outlet, reducing turbulence and preparing exhaust gases for the downstream catalytic converter or muffler. Installation hardware and gaskets are included, simplifying the retrofit process. Weighing 18.74 lbs per pair, these headers represent a straightforward bolt-on upgrade that maintains emissions compliance while enhancing exhaust gas evacuation compared to factory cast-iron manifolds.

Street-performance applications benefit most from these headers—daily drivers, weekend cruisers, and light off-road duty where reliability and ease of installation matter as much as incremental power gains. The black paint resists high-temperature oxidation, though long-term thermal cycling will develop a patina over time. Owners should verify fitment against their specific S-10 or compact truck variant before purchase, as engine bay clearances can vary by model year and engine configuration. These headers pair well with cat-back exhaust systems and are compatible with stock or upgraded cooling setups.
