Built To Handle Real Power Without Giving In

When you’re pushing a 6.7L Cummins hard, the last thing you want holding you back is a weak cylinder head. The Industrial PDM-67STH Street Performance Head is built for diesel owners who demand more from their trucks, more power, more durability, and more confidence under load. Whether you’re towing heavy, tuned for street performance, or just looking to replace a stock head with something tougher, this head is ready for the job. Each casting goes through a high-pressure wash and glass bead process to eliminate oil, grime, and carbon buildup right from the start. It’s then pressure tested and visually inspected to make sure there are no cracks or defects hiding inside. From there, the head is CNC ported using 5 Axis technology to ensure every intake and exhaust port is identical, helping your engine breathe better and run smoother. That consistent airflow across all six cylinders means better tuning, cleaner combustion, and more usable power on the street. If you’ve been burned by cheap castings or heads that crack under heat, this one’s designed to outlast and outperform.

Every Port Is Precision Engineered To Perform

The PDM-67STH is far more than just a cleaned-up casting. It’s the result of a highly controlled process that prioritizes both flow and strength, two things that often don’t go hand in hand. After the initial cleaning and inspection, valve guides and seats are removed as needed to allow full access for port development. Using a Superflow 600 flow bench, airflow data is logged and analyzed to shape each port with accuracy that simply can’t be done by hand. The real magic comes from the 5 Axis CNC machine, which uses CAD/CAM software to deliver repeatable port shapes with tight tolerances. This ensures each cylinder gets the same volume and velocity of air, which is crucial for consistent combustion and optimal tuning. What's more, port wall thickness is never sacrificed for the sake of high flow numbers. In high-performance diesel applications, where thermal shock is common, this attention to detail helps reduce the risk of cracking and failure over time. It's a smart investment for anyone building a reliable, power-focused Cummins setup.
