ISB Stage 1 24v Cummins Performance Head

Elevate your engine's performance with our ISB Stage 1 24v Cummins Performance Head. Designed to enhance power without the added cost and complexity of an aftermarket intake, this performance head combines the best of our industry-leading remanufactured cylinder heads with advanced features for superior performance.

Key Features:

  • Enhanced Valve Springs: Equipped with 105-pound valve springs for improved performance.
  • 5 Axis Port Job: Precision porting that retains the factory intake plenum, increasing intake flow from approximately 155 CFM stock to 220 CFM.
  • Performance Benefits: Increases low-end performance, reduces boost pressure, and lowers EGTs, allowing more fuel to be burned for greater power output.

Detailed Process:

  • Head Options: Choose to use your own head or one of our head cores.
  • Disassembly: The head is 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 Bronze Guides: All new bronze guides are installed for durability.
  • Heavy Duty Seats: Extra large seats placed on both intake and exhaust sides.
  • 5 Axis CNC Porting: Advanced CNC porting with the stock intake shelf in place for optimal airflow.
  • High Performance Valve Job: Precision valve job performed to enhance performance.
  • Resurfacing: The head is resurfaced to meet exact specifications.
  • Painting: Professionally painted for a durable finish.
  • Assembly: Assembled with all new valve seals, soft plugs, and HD springs.
  • Pressure Checking: Valves and coolant passages are pressure checked to ensure top quality.

*Cores must be in good condition with no cracks and must be rebuildable. D&J Precision Machine will inspect your core upon arrival to determine its suitability for rebuilding.
