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.
