This upgraded 6.4 Powerstroke diesel engine cylinder head is a great choice for those looking to take it a step above our Daily Driver model. These heads include all new parts and castings plus o-rings for increased head gasket sealing capability.

6.4 Powerstroke Remanufactured Diesel Engine Cylinder Heads Include:

• Surfaced Cylinder Head To Meet Or Exceed OEM Specification of Ra or Roughness Average, which maximizes sealing surface performance.
• New Cast
• New Valve Stem Seals
• New Valves Seats
• New Valve Guides
• New Valve Springs
• O-Rings
• Cut seats with 3 angles and optimize flow.

Machining Process: Our heads are blueprinted to proprietary valve train geometry, to alter valve height and valve recession for maximum reliability and longevity. Our Valve stem heights are altered to remove preload on the lifter and decrease the wear and help the lifter live a long life.

Inspection Process: Once our machining processes are complete, we pressure test the 6.4 Powerstroke cylinder heads with 40 PSI pressure to make sure there are no leaks.

Then we send it through another extensive cleaning, quality control inspection and sign off sheet that will include all specs of the heads. We measure the following specs by use of profilometer:

• Valve recessions
• Stem Heights
• Installed Spring Heights
• Spring Pressures
• Keeper and Lock Positions
• RA Recording

Tech Tip:

Be sure that the surface of the block is inspected and cleaned prior to installation of this Cylinder Head. 6.4 Workhorse Cylinder Head New Choate Part Number: CEP64WHN Fitment: 2008,2009,2010 F-Series Trucks Manufacturer: Choate Engineering Performance
