According to my sources, your oil pressure is spot-on. According to Lingenfelter's book, any small block chevy with a functioning lubrication system will get about 5-10 psi per 1000 rpms. Higher oil pressure is not necessarily better, nor does it mean more oil FLOW, it really just means that the oil pump has to work harder because the oil is more viscous. REALLY HIGH oil pressure is not a good thing performance wise since you are losing more power parasitically to spin the pump.
And yes, I agree with the others, it comes down after a while, after the oil heats up, because it thins out due to temperature.
