Power-Stroke Products Cylinder Heads

Power-Stroke Products Cylinder Heads: Built to Outlast the OEM Weak Points

When a diesel engine's cylinder head fails — whether from cracking, warping, or a blown head gasket — the repair is never trivial. For Ford Powerstroke and Cummins owners who want to do the job right the first time, Power-Stroke Products has become one of the most trusted names in the diesel performance and replacement cylinder head market. Based out of Bertram, Texas, this Made-in-the-USA brand was built around a deep understanding of the exact engineering shortcomings found in factory diesel top-end components.

Every Power-Stroke Products cylinder head in the cylinder heads category starts from a brand-new casting — never remanufactured or re-sleeved cores. Each casting undergoes a rigorous inspection process before assembly, ensuring dimensional accuracy before a single valve is installed. The finished heads are pressure-tested and surfaced, with the explicit goal of eliminating the cracking, warping, and sealing failures that have made OEM heads on platforms like the 6.0L and 6.4L Powerstroke notorious among diesel technicians and enthusiasts alike.

Configuration Options for Every Build Level

One of the most practical aspects of Power-Stroke Products' cylinder head lineup is the tiered approach to configurations. Most supported engine applications are available in multiple spec levels, including:

• Loaded Stock — Drop-in replacements assembled with new valves, springs, and seals. No core required, ready to install.
• Loaded Stock with Heavy-Duty Valve Springs — Ideal for trucks running upgraded turbos or mild tuning, where stock spring rates become a limiting factor.
• Loaded Stock with O-Ring — Features a precision-machined O-ring groove around the combustion chamber to improve head gasket sealing and keep combustion pressure out of the cooling system.
• O-Ring with Heavy-Duty Valve Springs — The top-tier street and performance configuration, built to handle increased boost pressures and higher RPM operation.

For the 2003–2007 Ford 6.0L Powerstroke specifically, Power-Stroke Products also offers a ported performance head that flows an impressive 200 CFM, supporting extreme builds that push serious power. These heads are assembled with performance valve springs and precision-machined for O-rings, and must be paired with MLS (Multi-Layer Steel) head gaskets for optimal sealing.

Coverage Across Major Diesel Platforms

Power-Stroke Products cylinder heads cover a wide range of the most popular diesel engines on the road. Ford Powerstroke applications include the 6.0L (2003–2007), 6.4L (2008–2010), and 6.7L platforms, as well as Cummins-powered trucks including the 5.9L and the 2019–2024 6.7L. The 6.7L Cummins head, for example, ships fully assembled with OEM valves, seats, seals, heavy-duty 103 lb valve springs, and retainers — making it a direct drop-in for worn or cracked factory units. Fitment details such as dowel size (18mm vs. 20mm on 6.0L applications) are clearly specified, helping builders avoid costly mismatches.

Warranty and Installation Notes

All Power-Stroke Products cylinder heads are backed by a 1-Year Unlimited Mileage Warranty. It's worth noting that a hot re-torque after initial break-in is required to maintain warranty coverage on all Power-Stroke heads — a standard best practice for any serious diesel top-end rebuild. Whether you're restoring a work truck to reliable daily-driver status or assembling a high-boost performance build, Power-Stroke Products offers a cylinder head configuration purpose-built for the task.
