Do you want to push the performance of your 6.7L Cummins? The D&J Precision Machine Stage 1 Performance Head is built to take the limitations of the factory cylinder head airflow restrictions, heat management issues, and long-term durability concerns and replace them with a setup that’s designed to perform under real diesel conditions.
This is for people running upgrades or just wanting confidence in their top end. It delivers improved airflow and combustion efficiency, helping your engine breathe easier and stay more stable under load. The result is a stronger, more consistent performance without sacrificing drivability, making it the perfect step up from stock.
Each Stage 1 head starts as a fully remanufactured casting, completely disassembled, cleaned, inspected, and precision-machined to restore critical tolerances. Advanced CNC machining and valve work improve airflow characteristics while ensuring proper sealing and consistency across all cylinders.
This head is upgraded where it matters most, with airflow improvements and valvetrain enhancements designed to handle the added demands of boost and load. The port design is optimized to move more air efficiently through the head, while upgraded springs and reinforced sealing areas help maintain control and reliability when cylinder pressure and heat increase. The result is a setup that not only flows better than stock but also holds up under the kind of stress that comes with towing, tuning, and real-world diesel use.
