How can I tell if my head gasket is stuffed?

Without pulling the whole farking bike to bits ideally as I don't really have the facilities here to do a proper job even if I had the mechanical competence...
I have an oil leak and shes overheating, suspecting head gasket but noticed coming back from Cranny the other day that the thermo fan isn't working so that will explain the overheating anyways...
All ideas appreciated
