Interesting sheet.
 If they are correct in it being a '1960' head, there were only 2: 536109 - regular head 535461 - SD head The SD head had bigger valves not sure if the intake port opening was bigger though without looking it up.

If the heads are 1960 models, 59-60 heads will be compatible with the intake
