Product Details & Specifications
Fits Marine Application Cummins 8.3L 12V 6C, 6CT Engines with 21" Air Intake Opening. 

If your engine is not in a marine application, please order part number 3936151 instead. 

Loaded cylinder head. Assembled, tested and machined in the US! This item will arrive with a full valvetrain assembly and injector cups already installed. You will just need to swap your own injectors over.  

Cylinder head casting and all components are brand new. There is no core charge associated with this item.

Please note: Because most applications require a port on the left hand side of the cylinder head, it comes pre-drilled with a hole in this area for proper location. If your engine does not require the use of this port, you will need to tap this hole with a 1/2" pipe thread and install a plug.
