The factory manual says that you should have 70 psi when fully warmed 
up.  If you have less than this there is an adjustment on the oil 
pressure regulator spring.  Please note that if you did not replace this 
spring then you are never going to get the oil pressure right as the old 
one is worn out though age, heat, and rubbing against the side of the 
bore it rides in.

If you cannot achieve 70 psi with good oil on a "rebuilt" engine then 
you have other problems such as incorrect bearing clearance, worn oil 
pump etc.  On a good engine it is easy to get over 100 psi at 2,000 rpm 
though not recommended by anyone including me.
