I did a run of about 60 miles in the Ulster this morning (standard jet feed and oil pump, 20/40 oil) and the oil pressure reading was a bit higher than normal. On stopping after 25 miles the radiator header tank was warm but by no means hot. I don't worry too much about the oil pressure. It's a bit like your blood pressure, if you worry about it too much you will bust a blood vessel!
One thing never to forget is that water temperature and oil temperature are two entirely different things. It's quite possible to have the radiator boiling away merrily and the oil in the sump still cold.
