Improved Durability and Reliability for 6.7L Cummins

If you're pushing your 2019-2024 Ram 6.7L Cummins to work harder—whether for towing, daily driving, or performance upgrades—you need a cylinder head that can keep up. The factory head does the job, but when you start adding more power, higher boost, and heavier loads, it can become a weak link. The BD Diesel Stage 1 Performance Cylinder Head is built to handle those demands with upgraded components, improved airflow, and a reinforced design that delivers both reliability and efficiency. One of the biggest improvements in this head is the 5-axis CNC porting. Unlike stock heads that can restrict airflow, this precision-machined design increases intake flow from 155 CFM to 220 CFM. That extra airflow helps the engine breathe better, improving throttle response and reducing turbo lag. With better combustion efficiency, you’ll also see lower exhaust gas temperatures, making this an excellent upgrade for trucks that tow heavy loads or run high-performance tuning.

Improved Strength and Durability

Durability is another major focus of this cylinder head. The factory valve seats have been known to fail under extreme heat and pressure, leading to costly engine damage. BD Diesel addresses this with upgraded hardened valve seats that resist cracking and loosening over time. Bronze valve guides are also installed for added wear resistance, ensuring a longer lifespan even in high-stress conditions. Stronger valve springs are another key upgrade. This head comes equipped with 105-pound valve springs, which are designed to prevent valve float at higher RPMs and boost levels. If you’re running a modified fuel system or a larger turbo, these springs help keep your valvetrain stable, so you don’t lose power or risk component failure under load.Despite these performance upgrades, installation remains simple. It’s a direct bolt-on replacement for the stock unit, making it easy to upgrade without extensive downtime. Every head is fully machined, crack-checked, resurfaced, and pressure-tested before it leaves the shop, ensuring you get a high-quality component that’s ready to go.
