The Hedman 64-72 GTO/Lemans 326-455 headers are purpose-built exhaust manifolds designed specifically for A-Body Pontiac V8 engines from the muscle car era. These headers are ideal for classic Pontiac owners looking to enhance performance and responsiveness without extensive modifications.
Constructed from mandrel-bent steel tubing with a professional black powder-coat finish, these headers feature a standard configuration of 1.75-inch primary tubes that expand into 3-inch collectors. This design balances scavenging efficiency across various Pontiac V8 platforms, ensuring smooth exhaust gas velocity and reduced back pressure.
Mechanics and hobbyists will appreciate the straightforward installation process, as all necessary gaskets and mounting hardware are included. These headers are particularly beneficial for those optimizing their vehicles for performance, making them a great addition to any 1964–1972 A-Body Pontiac project.
