1936 Series 60 Head Bolts/Studs

I pulled the head off my '36 several years ago and forgot to mark the headbolt locations. There are (4) studs with nuts on top that are used for head bolts but I don't know where. I found a location for 2 - they capture the brace for the big air cleaner on the front/left.

Does anyone know where the other two studs are used??

Thanks!

Just came from the garage. On mine the front bolts are studs with nuts, and the 7th back on the drivers side, the 9th back on the pass side. I really don't think it matters they are probably there to help set the head on in the right position. As you know by now, it is heavy.
