BD Diesel Performance Cylinder Head (Stage 1) Dodge/Ram 6.7L Cummins 19-24

The Stage 1 Performance Cylinder Head is designed to increase airflow, boost efficiency, and enhance power while retaining the factory intake plenum for a seamless installation. Featuring 105-pound valve springs and a 5-axis CNC port job, this upgraded head improves intake flow from 155 CFM to 220 CFM, reducing boost pressure and lowering EGTs for better overall engine performance. With hardened valve seats, bronze guides, and a precision CNC valve job, this cylinder head is built for reliability and durability in high-performance and towing applications.
