Once the 6.6 Duramax Diesel Engine cylinder head passes our rigorous inspection for cracks and imperfections through MPI testing, it will go through a stress relieving process in a furnace to turn any grease and oil into ash.
Then we shot blast it in our cabinet to remove any rust and scaling. This will also relax the material before machining to our specifications.
After this, we check it for any broken bolts or studs, and remove them.
Once it has met our stringent standards, it will then start through the machining process.
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 6.6 Duramax 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:
Be sure that the surface of the block is inspected and cleaned prior to installation of this Cylinder Head.
Warranty:
6 Months warranty on Cylinder heads. Parts warranty only.
Building engines the way the OEM factory should have in the first place.
