71-91 Sb Mini Motorhome

The Hedman 71-91 Small Block Mini Motorhome Headers are purpose-built exhaust manifolds designed for mechanics and enthusiasts upgrading compact recreational vehicles powered by small block Chevrolet engines. These headers replace restrictive factory cast-iron manifolds, significantly improving exhaust scavenging and engine breathing for vehicles built during the 1971–1991 production window.

Hedman headers utilize mandrel-bent tube construction to maintain consistent diameter and eliminate turbulence that kills horsepower and torque delivery. The small block-specific design optimizes collector angle and primary tube sizing for the displacement and RPM band typical of motorhome applications, where reliability and consistent power matter more than peak dyno numbers.

Motorhome owners, vintage RV restorers, and small block Chevrolet mechanics benefit most from this bolt-on upgrade, which requires no extensive fabrication or exotic tuning knowledge. Installation involves unbolting the factory manifolds and fitting the header flanges, making it a straightforward enhancement for improved performance.
