Jim,
I purchased the head from AK Miller many years ago. He cut one cylinder off each end of the head and welded a plate to each end. His customer then lost interest in the project so AK shelved it and when I was buying something else from him he told me about it so I purchased it because the price was cheap. It has a Ford casting number on it. They look similar to a Cleveland head. The bore spacing and head bolt pattern are the same as the Tempo 2.3L block.
