Gasket Kit Help

Rebuilding my 74 cb360 motor and got a new gasket kit. In with the valve seals are 2 small O-ring washers and I can't figure out where they go. They are not the O-rings that go behind the oil pump as those are already installed. Anybody know where these things go as I am stumped.

What size are they? Cross reference it with a pretty complete list that Lee compiled on Hondatwins.net: http://www.hondatwins.net/forums/47-manuals-technical-documents/6490-cb360-oil-seal-gasket-list.html
