IMO, changing relief valve springs or oil viscosity before you do the above is wasting time and money and possibly counter-productive.
Yes I agree, a high volume oil pump will create more pressure because the restrictions haven’t changed. Everyone I’ve talked too says this pressure is typical of a high volume pump. When the oil heats up, the pressures should drop 20 psi. That’s is what some life long engine builders have said.
