ok, so I removed te overs and took pics. Did not find any casting numbers but did find the following. First two pics show the "saw tooth" and "hump" shapes which are used to identify if you have 906 or 062. As you can see, each head has both marks go figure.

the last pics show the stamps on the head which dont look like a GM stamp. Does anyone know what they mean?
