INDUSTRIAL INJECTION PDM-59CRSTH DODGE PERFORMANCE HEAD FOR 03-07 5.9L CUMMINS

The Industrial Injection 5.9L Cummins Performance Heads are designed for the daily driver / weekend warrior in mind. Fully CNC ported heads complete and ready to bolt on.

CNC Ported Cylinder Head:

The porting process preformed uses a new 5 Axis CNC Cylinder Head Porting Machine with CAD/CAM software specifically designed for cylinder head porting. CNC porting brings unparalleled accuracy to head porting with each port flowing the same. This helps balance the power that each cylinder produces, making tuning easier. After the CNC process we then hand blend each port to perfection.

New Performance Stainless Steel Valves:

We use the highest quality upgraded stainless steel valves with a nitrate coating for ultimate durability to out-perform and outlast any aftermarket or OE valves available. High Strength Alloy Valve Guides:New High Strength Alloy, Heat Treated iron based valve guides are installed.

These guides are heat treated to Rockwell 22 C Scale, which produces the ultimate in wear resistance. This is far superior to original guide material, including Bronze. The guide incorporates a spiral grove inside the guide to hold oil and aid the lubrication of the valve during engine operation. 

Performance High Temp Valve Seats:

Premium valve seat inserts made from a true Nickel Based Non-Magnetic material that was developed for extreme operating conditions. These performance valve seats immensely reduce the possibility or dropping a valve seat.

Drilled and Tapped Coolant Freeze Plugs In Head:

The factory head has press in freeze plugs that are prone to leaking and blowing out under the valve cover. This process eliminates the failure from ever happening to you with our cylinder heads. We use high quality steel plugs where others use aluminum that are prone to leak.

Fire Ringed Head:

The fire ringed head procedure was designed to use with our custom fire ring head gasket which utilizes a radius cut steel fire ring to virtually eliminate head gasket failures while still allowing you to daily drive your vehicle with confidence in its longevity capabilities.

Valve Springs:

We use the highest quality brand new performance 95lb valves springs custom made right here in the USA. We designed these springs to offer more lift than the competition. Each valve spring is tested multiple times in house before assembly to ensure it maintains it proper spring rate.

The Build Process:

Heads are first jet washed in a high pressure spray cabinet to remove oil and dirt, then glass beaded to remove carbon. Next they are checked by magnafluxing, (cast iron only) or pressure testing. They are visually inspected for defects that would make them unusable. Valve guides and seats are removed as needed for porting.

Port development is accomplished using a superflow 600 flow bench with a computer recording all flow measurements.Many things are considered when designing a cylinder head Port; air flow is only one of the things to think about. Another major concern is port wall thickness.

Anyone can get a head to produce high flow numbers, but if doing so leaves the port wall to thin the casting will crack. High performance Diesel heads are more prone to crack because of the thermal shock experienced by excessive intermittent or long term exhaust temperatures.

The porting is then preformed using a new 5 Axis CNC Cylinder Head Porting Machine with CAD/CAM software specifically designed for cylinder head porting. CNC porting brings unparalleled accuracy to head porting with each port flowing the same. This helps balance the power that each cylinder produces, making tuning easier. New High Strength Alloy, Heat Treated iron based valve guides are installed.

These guides are heat treated to Rockwell 22 C Scale, which produces the ultimate in wear resistance. This is far superior to original guide material, including Bronze. The guide incorporates a spiral grove inside the guide to hold oil and aid the lubrication of the valve during engine operation.

Guides are then honed (not reamed) to exact size using a diamond honing mandrel. Diamond abrasives allow for consistency of size, surface finish, and bore geometry with no variation from guide to guide. The guide size is then verified using a valve guide bore gauge.

As needed the head receives new Premium valve seat inserts made from a true Nickel Based Non-Magnetic material that was developed for extreme operating conditions. Next the head is treated to a multi angle valve job to help maximize the flow of air in and out of the head.

This is accomplished using a Serdi 100 guide and seat machine. Serdi uses a solid carbide straight shank pilot. When inserted into the valve guide, it simulates the real valve stem during the centering process.

This guarantees the valve seat is finished for a perfect valve to seat match. Using CBN or Diamond tooling the head is given a new surface. With our berco milling machine we can control the surface finish to accommodate different head gasket types.

For example MLS head gaskets require a very smooth surface finish. Finally the head is jet washed dried and assembled with new valve seals and new performance valve springs.

The Industrial Injection PDM-59CRSTH Dodge Performance Head is meticulously crafted for the discerning 2003-2007 5.9L Cummins diesel enthusiast who demands reliability and peak performance. Designed with the daily driver and weekend warrior in mind, this fully CNC-ported head is ready to bolt on, transforming your engine's capabilities effortlessly.

Utilizing state-of-the-art 5-axis CNC technology and CAD/CAM software for unparalleled precision, each port flows consistently, ensuring optimal power balance across all cylinders. After this advanced CNC porting, expert hand-blending fine-tunes each port for maximum airflow performance. The inclusion of premium stainless steel valves, coated with nitrate for unmatched durability, elevates the performance beyond standard aftermarket options, while high-strength alloy valve guides are heat-treated for superior wear resistance.

Unlike factory models, the Industrial Injection head features drilled and tapped coolant freeze plugs, eliminating the risk of leaking and enhancing reliability. The fire-ringed design pairs seamlessly with a custom fire ring head gasket, virtually eliminating head gasket failures, which is essential for those who push their engines to the limit.

Quality extends to every aspect with 95lb performance valve springs, rigorously tested for consistency in lift and pressure. The meticulous build process involves jet washing, glass-beading, and thorough inspections, ensuring each head is free of defects before being honed with diamond abrasives for exact sizing.

Designed to withstand extreme operating conditions, the nickel-based valve seats offer enhanced temperature tolerance while maintaining structural integrity through thermal shocks. Elevate your Cummins’ performance with confidence, knowing that the Industrial Injection PDM-59CRSTH head is engineered for both durability and efficiency, providing the power you crave without compromising reliability or longevity.
