The 65-76 Olds Cutlass 455 headers by Hedman are designed for classic muscle car enthusiasts looking to enhance the performance of their Oldsmobile 455 big-block engine. These headers are engineered to unlock horsepower and torque while improving exhaust flow, making them ideal for both restoration projects and performance builds.
Constructed from durable mandrel-bent steel, these headers minimize turbulence and optimize exhaust scavenging. The design features an optimized collector that reduces back-pressure, ensuring efficient power delivery across the engine's RPM range. Quality welds and robust materials ensure longevity and reliability in high-heat environments.
These headers are compatible with 1965–1976 Oldsmobile Cutlass models equipped with the 455 cubic-inch engine, accommodating both automatic and manual transmissions. This makes them a versatile upgrade for enthusiasts looking to restore original performance or enhance their classic muscle car's capabilities.
