The Story
This complete cylinder head is assembled using a combination of new OEM and high-quality aftermarket components, guaranteeing reliable operation and longevity. This listing is for 1 cylinder head.
- New Casting: Built from a brand-new, non-remanufactured casting.
- New Valves: Equipped with new, high-quality intake and exhaust valves that are inspected for proper seating and clearance.
- New Valve Springs and Retainers: Utilizes brand-new valve springs matched to the engine's requirements and durable retainers and locks for secure operation, even at higher RPMs.
- New Injector Cups: Pre-installed new injector cups for proper fuel sealing.
- O-Rings: For enhanced durability, o-rings are cut and installed into the deck surface to dramatically improve sealing under high cylinder pressures.
Ā
Key Features and Fixes
This head features key performance and durability upgrades, backed by an intense inspection protocol to guarantee every specification is met.
- Pressure Testing: After machining, every cylinder head is pressure tested at 40 PSI to confirm zero leaks and ensure casting integrity.
- Blow-Proof Plugs: Threaded, blow-proof plugs are installed in the top of the head for increased security and leak prevention.
- Final Quality Control: The head undergoes a final, extensive cleaning and quality control inspection. A detailed sign-off sheet is generated, measuring and recording critical specifications using a profilometer, including:
- Valve Recessions
- Stem Heights
- Installed Spring Heights
- Spring Pressures
- Keeper and Lock Positions
- RA Recording
This rigorous process ensures you receive a head that is significantly improved over the original and ready for years of demanding diesel operation.
Ā
Machining Process:
Choate Engineering Performance has incorporated critical modifications and features to address common failure points of the factory 6.0L Powerstroke cylinder heads, drastically improving reliability.
- Optimal Sealing Surface: The deck is resurfaced to meet or exceed OEM specifications for Roughness Average (Ra), maximizing the sealing surface performance for the head gasket.
- Valve Train Geometry Alteration: We custom blueprint the head to alter valve height and valve recession, achieving maximum reliability.
- Lifter Longevity Fix: Valve stem heights are precisely altered to remove preload on the hydraulic lifter. This crucial modification decreases wear and significantly extends the life of the lifters.
- Optimized Flow: Valve seats are cut with a three-angle profile to optimize airflow and ensure proper sealing.
- Valve Prep: Valves are reground and their margins are meticulously inspected to guarantee proper sealing against the new seats.
- New Components: New casting, valve stem seals, valve seats, and valve guides are installed.
- O-Rings: For enhanced durability, o-rings are cut and installed into the deck surface to dramatically improve sealing under high cylinder pressures.
