85-90 Amc Wagoneer 360

The Hedman 85-90 AMC Wagoneer 360 headers deliver optimized exhaust flow for full-size AMC V8 performance. This pair of street headers features 1.75-inch primary tubes stepping up to a 3-inch collector, engineered specifically for the 360 cubic-inch engine found in 1980–1988 Wagoneer models. Constructed from durable steel with black paint protection, these headers improve scavenging efficiency while maintaining street-friendly compatibility. Gaskets and hardware are included for a complete installation package.

The 1.75-inch primary tube diameter optimizes mid-range torque delivery characteristic of the 360 V8, while the stepped 3-inch collector consolidates exhaust gases and reduces backpressure—a critical factor in improving cylinder scavenging and overall engine breathing. The black paint finish resists rust and weathering, essential for full-size SUV and truck applications where underbody exposure demands corrosion resistance. At 25 pounds for the pair, these headers represent a significant weight penalty compared to cast iron manifolds, but the exhaust efficiency gains offset this in drivability and responsiveness.

Buyers restoring or modifying 1980–1988 AMC Wagoneer models with 360 engines will find these Hedman headers essential for street-driven builds. Whether upgrading from original cast manifolds or replacing worn headers, this pair addresses the common challenge of improving exhaust flow without sacrificing the vehicle's streetable character. Installation requires standard engine bay clearance and exhaust system coordination, making fitment verification critical before purchase.

Hedman has established itself as a trusted source for AMC performance headers, with proven application across full-size Jeep and Wagoneer platforms. These street-rated headers balance ease of installation with measurable exhaust efficiency for owners seeking reliable V8 performance in classic utility vehicles.
