Holden Torana LH L34 308 V8

Custom Headers L34 (extractors) are a reproduction of the original race-style headers fitted to the rare Holden Torana LH L34. These headers are made to order and replicate the unique factory performance design used on the homologation L34 Torana models. Suitable for LH–LX Torana 253 & 308 V8 engines, they are ideal for authentic restorations, historic race builds, and high-performance street cars.

Precision-engineered to match the layout and flow characteristics of the original L34 headers, these extractors improve exhaust scavenging, increase torque, and sharpen throttle response while maintaining the distinctive appearance of the original factory race components.

Brief History – Holden Torana L34

The Holden Torana LH L34 was a special homologation model produced in 1974–1975 so Holden could compete in Australian touring car racing. Around 260 vehicles were built to satisfy Group C racing regulations, making the L34 one of the rarest and most collectible Torana models.

Powered by a high-performance version of the 308 cubic inch Holden V8, the L34 featured upgraded cylinder heads, larger valves, strengthened bottom end components, and unique exhaust headers designed to improve airflow and power at racing speeds. These cars were developed specifically for Bathurst and touring car competition and later evolved into the legendary A9X Torana.

Original L34 components, including the distinctive headers, are extremely rare today. These reproduction headers allow enthusiasts to recreate the correct appearance and performance of the historic L34 race package.
