The newer engines do not even have a spec for idle pressures. They only test them at 1500-2000 rpm. I believe that the oil pressure lights come on when pressures get below 3 psi. The pressures you are getting sound fine to me. My 283 runs about 15-20 psi cold idling and about 45 psi cruising at 50 mph.
