Description

The PDM-67RHS3 is Industrial Injection's Stage 4 race head for the 2007.5-2018 6.7L Cummins — the top of the race head ladder. Fully CNC-ported with fire ring grooves, custom-port oversized 34mm valves, and concrete-filled water jackets to reinforce the deck against extreme cylinder pressure. Built for sled pullers and racers where head deformation is the limiting factor.

Part Number: PDM-67RHS3

Features

  • Stage 4 race head — concrete-filled
  • 5-axis CNC porting on intake and exhaust ports
