I think air does the majority of the cooling, but it only cools the
outside of the heads and cylinders.  The oil cools the inside of the
engine, which is also critical.  Contrary to what Michael saw, I noticed
only a slight increase (if any) in oil temp when I went from dino oil to
synthetic.  Still, I'm staying away from synthetic for now because of
it's supposed reduced specific heat (is that the right term?).
