RCD 6.0L Ford Power Stroke CNC Ported Cylinder Head
CNC ported to provide up to 30% more airflow, delivering substantial gains in volumetric efficiency, lower EGTs, and increased horsepower potential—especially when combined with upgraded turbos, injectors, or tuning.
Includes 1 mm oversize exhaust valves and 120# valve springs installed for improved performance and valvetrain stability.
Optional stainless steel O-ring groove available for enhanced head gasket sealing, virtually eliminating common failures under high boost and combustion pressures.
Manufactured from high-nickel content castings for superior strength and durability.
Reinforced injector bores to prevent cracking and ensure long-term reliability.
Hardened valve seat inserts designed to resist cracking under extreme conditions.
Heavy-duty valve guides for superior wear resistance and extended lifespan.
Fully machined in-house using state-of-the-art CNC equipment for precision and consistency.
Upgraded deck surface and design elements for optimal head gasket retention.
Blueprinted valvetrain geometry for precise valve recession, maximum reliability, and longevity.
Expertly assembled with premium components, including new USA-made valve springs, retainers, locks, valve stem seals, freeze plugs, glow plug sleeves, and injector sleeves where applicable.
Proven performance in demanding applications.
No core charge or return shipping required, as heads are built to order or new.
Take your 6.0L Ford Power Stroke to the next level with our RCD CNC-ported cylinder heads, engineered for serious performance without sacrificing reliability. These heads start with high-quality, high-nickel content castings built to withstand the demands of tuned and boosted applications. We've incorporated reinforced injector bores and strengthened bolt holes to eliminate common factory failures like cracking and fuel dilution in the coolant, while hardened valve seat inserts prevent the cracking issues that plague stock heads.
Each head undergoes precision CNC porting in-house, optimizing the intake and exhaust runners, bowl areas, and valve seats to achieve up to 30% more airflow compared to stock. This boost in air velocity reduces turbulence, improves combustion efficiency, and unlocks real-world power gains—often 100+ horsepower when paired with supporting mods like larger turbos or injectors, with high-horsepower diesel builds frequently exceeding 900-1,000 hp on ported setups.
