The 2003-2007 5.9 Stage 1 Cummins Performance Cylinder Head is designed to deliver increased airflow and durability without the added cost and complexity of an aftermarket intake. Featuring 105-pound valve springs and a 5-axis CNC port job, this head significantly boosts intake flow from 155 CFM to 220 CFM, improving low-end performance, reducing boost pressure, and lowering EGTs.
Built on the foundation of the HP Reman Head, it includes new bronze guides, oversized hardened seats, and a high-performance CNC valve job for enhanced longevity and efficiency. Manufactured by D&J Precision Machine, this cylinder head is a proven upgrade for both stock and performance-driven Cummins builds.

No Core Return Required
This is a remanufactured unit. In North America it carries a core charge — a deposit you get back only by shipping your old unit to the manufacturer. Returning a core from Australia is not practical, so we have built that cost into the price and you keep your old unit. There is nothing to send back, no deposit to chase, and no surprise on the invoice. The price you see is the price you pay.
