I wouldn't read too much into his revs dropping, more likely the oil pressure is a symptom of that rather than the other way round - have his pressure relief valve out for a clean up 'n think about adding a little packing behind the spring to raise his cold pressure to 60-70 psi, that should bring up the warm pressure too. Does he make oil pressure straight away when you start him?
