They only part number is P4532900. They are raw castings, seats have not been cut or installed you can build them to your own specs.

Comment taken from Hughes Engines concerning the mopar magnum heads..LOL

3. The factory aluminum, this head, in our opinion, was designed by a person or group that had no idea of what they were doing or how to do it, and we will waste no more of your time or our web site discussing it!
