I have a NEW head, never installed. My dad's machine shop had to be sold at auction last Saturday. I only bought this head to resell it and send my mom the money. My dad has terminal cancer. He said that he believes it is for a Nash Rambler. The head casting number is 3143892. I am trying to identify this head, and it is for sale. If anyone can help it would be greatly appreciated. Thanks, Rotten
