Stage 2 6.7 CR Cummins Performance Head

Our Stage 2 6.7 CR Cummins Performance Head is designed for the performance enthusiast. It includes everything in our Stage 1 Cummins Performance Head plus a D&J Stage 2 6.7 CR Billet Intake Manifold, thread-in soft plugs in the head, titanium valve spring retainers, and heavy-duty extra-large valve seats.

Key Features:

  • Upgraded Valve Seats: Our heavy-duty extra-large valve seats address the issue of stock seats falling out, ensuring durability and reliability.
  • Thread-In Soft Plugs: Prevents soft plugs under the valve cover from coming out and filling the crankcase with coolant.
  • Billet Intake Manifold: Designed to keep the factory MAP sensor, air horn, and throttle position sensor. This manifold ensures more even air distribution, preventing hotspots and potential piston melting.
  • Increased Airflow: Intake flow increased to 250 CFM, compared to the stock 165 CFM, providing enhanced performance.
  • Comprehensive Upgrades: Includes all features of our Stage 1 Cummins Performance Head.

Detailed Process:

  • Replacement Style Billet Intake: Stage 2 includes a replacement style billet intake manifold.
  • Complete Disassembly: The head is completely disassembled, and all soft plugs are removed.
  • Cleaning and Blasting: Thorough cleaning and blasting to ensure a pristine surface.
  • Crack Check: Performed to ensure structural integrity.
  • New Components: Installation of all-new bronze guides and heavy-duty extra-large intake seats.
  • 5-Axis CNC Porting: Performed for optimal airflow.
  • Thread-In Soft Plugs: Installed under the valve cover for enhanced reliability.
  • High-Performance Valve Job: Precision CNC valve job performed for enhanced performance.
  • Resurfacing: The head is resurfaced to meet exact specifications.
  • Thorough Cleaning: Comprehensive cleaning process to eliminate all debris.
  • Expert Assembly: Assembled with all new valve seals, thread-in soft plugs, 115# springs, and titanium retainers.
