Description

The Industrial Injection LB7 Duramax Stock Remanufactured Heads with Torque Lock Cups are an upgraded factory replacement.

Each head undergoes a multi-angle valve job for optimized airflow and is surfaced with a Berco milling machine for a precise finish. Sold in pairs, these heads are designed for a direct bolt-on installation.
