Oil seal rings around head gasket

[Anonymous]

i am currently rebuilding my 1978 gs400 twin and as i was rebuilding it i remembered along with the head gasket went four red rings around the outer studs to seal the oil going to the cams from leaking into tha head when i took it apart there was a small amount of oil absorbed into tha edge of the head gasket and i know they need to be replaced PROBLEM IS the gasket kit came with everything emagined but not these i am stuck and i dont understand i dont even know what to call them

The oil control o-rings can be purchased genuine or just get o-rings from an auto parts that fit the holes in the head gasket.
