oil pressure relief valve?

At what pressure does the oil relief valve kick in and what is too high of a pressure reading?

When the engine is at temp, I have proper pressure readings but on a cold engine they seem high to me. Cold idle 40psi and if I have to accelerate hard I've seen it up to 60psi. Pump was resurfaced & valve was cleaned 2 yrs ago when I did the top end. Both gauge & sender are VDO.

Talked to my mechanic yesterday when picking the Rover from her yearly inspection. He said not to worry about 60psi and thought the PRV did not kick in until 70 or higher.
