The + and - marks out on the ends is interesting but since they are cast in, doubt they mean much. Wonder if these same + and - marks are common on all '64 heads in that location. might not be unique to the 9770716 heads.
Not unique to the 9770716 heads, my 9773345 326 heads have those same markings on the end pads.
