The Industrial Injection PDM-59RHC Cummins 5.9L CR Stage 3 Cylinder Head for 2003-2007 Cummins 5.9L 24V engines is a top-of-the-line product meticulously crafted to enhance performance and durability. This fully CNC ported cylinder head is designed to deliver outstanding results, offering a seamless bolt-on installation process.

Featuring a CNC ported cylinder head that has been meticulously milled off intake runners to accept ZZ Fab intake, each port is intricately crafted using a cutting-edge 5 Axis CNC Cylinder Head Porting Machine with CAD/CAM software. This precision porting process ensures uniform flow across all ports, facilitating balanced power distribution and simplified tuning. Furthermore, post-CNC porting, each port is hand-blended to perfection for optimal performance.

The inclusion of custom port oversized 36mm stainless steel valves, boasting a nitrate coating for superior durability, sets this cylinder head apart. The high-quality alloy valve guides, heat-treated to Rockwell 22 Scale and featuring an internal spiral groove for enhanced lubrication, offer exceptional wear resistance. Additionally, the high-temp valve seats crafted from a premium nickel-based non-magnetic material are engineered to withstand extreme operating conditions, minimizing the risk of valve seat failure.

Addressing common concerns, the cylinder head comes with drilled and tapped coolant freeze plugs to prevent leaks and blowouts that can occur with standard press-in plugs. Moreover, the fire ringed head design, compatible with a custom fire ring head gasket, virtually eliminates head gasket failures while ensuring longevity and reliability for daily driving.

Boasting brand new 120lb valve springs made in the USA, specially designed to offer superior lift and meticulously tested to ensure consistent spring rate, this Industrial Injection cylinder head is a testament to quality craftsmanship and high-performance engineering.
