Description

The Industrial Injection PDM-59RHC is a Stage 2 fully CNC-ported cylinder head for the 2003-2007 5.9L Common Rail Cummins, aimed at racers and sled pullers running larger-bore short blocks. It carries oversized 34mm performance stainless steel intake/exhaust valves, high-strength alloy valve guides, drilled-and-tapped steel coolant freeze plugs, and 120 lb performance valve springs. The intake runner is milled to accept a ZZ Fab intake.
