1998.5-2002 Dodge 24V 5.9L Cummins


The Industrial Injection 5.9L 24v Cummins Race Heads are designed for the racer/sled puller in mind. Fully CNC ported heads complete and ready to bolt on.

The porting process performed 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.

Part Number:  PDM-24VRH

Features
  • Porting process performed uses a new 5 Axis CNC Cylinder Head Porting Machine with CAD/CAM software specifically designed for cylinder head porting
  • Industrial Injection uses the highest quality upgraded stainless steel valves with a nitrate coating
  • Heat Treated iron-based valve guides are installed
  • Premium valve seat inserts are made from a true Nickel Based Non-Magnetic material
  • High-quality steel plugs whereas others use aluminum that is prone to leak
  • Highest quality brand new performance 120lb valves springs
  • Fire Ringed Head to eliminate head gasket failure

  •  

    High Strength Alloy Valve Guides:

    New High Strength Alloy, Heat Treated iron-based valve guides are installed. These guides are heat treated to Rockwell 22C 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 are made from a true Nickel Based Non-Magnetic material that was developed for extreme operating conditions. These performance valve seats immensely reduce the possibility of dropping a valve seat.

    Drilled & 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 Industrial Injection cylinder heads. They use high-quality steel plugs whereas others use aluminum that is prone to leak.

     

    Valve Springs:

    Industrial Injection uses the highest quality brand new performance 120lb valves springs custom made in the USA. They 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 its proper spring rate.

    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; airflow 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 too 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 performed 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 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 with 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 centring 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 Industrial Injection 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.
