Unlock More Power and Reliability with the Stage 1 Cylinder Head

If you're building out a high-performance 6.7L Cummins, you need a cylinder head that can handle the added power without sacrificing reliability. The BD Diesel Stage 1 Performance Cylinder Head is designed for truck owners who want increased airflow, stronger components, and a direct bolt-on upgrade—all without the added complexity of a fire ring setup. Whether you're pushing more boost, running bigger injectors, or simply upgrading for peace of mind, this head is built to deliver both strength and efficiency. One of the standout features of this head is its CNC-ported design. Unlike stock or remanufactured heads that stick to factory airflow numbers, this one is precision-machined to optimize intake and exhaust flow. By reducing air restrictions, it helps the engine breathe better, improving throttle response, fuel efficiency, and overall power output. If you're running a tuned truck, this improved airflow can also help lower EGTs by allowing more efficient combustion.

Heavy-Duty Valve Springs and High-Quality Hardware

To keep up with increased boost levels and higher RPMs, BD Diesel equips this head with upgraded valve springs. These stronger springs prevent valve float, which can rob power and cause reliability issues at higher engine speeds. Paired with stainless steel valves and hardened valve seats, this setup is built to handle the added stress of performance applications. Unlike stock valve seats, which have been known to loosen over time, these hardened seats are designed to stay put even under extreme conditions, preventing costly engine damage. One thing to note about this version of the Stage 1 Cylinder Head is that it does not come with a fire ring. Fire rings are typically used in extreme horsepower builds where combustion pressures are significantly higher than stock. If you're building a truck for daily driving, towing, or moderate performance upgrades, this head is more than capable of handling the power without the need for additional sealing modifications. The lack of a fire ring also simplifies installation, making it a great option for those who want a performance upgrade without extensive machine work or custom gaskets.
