New motor running 80 oil pressure-is it to high?

I recently built a 400- 470 stroker and still after about an hour running time it still has 80 oil pressure . After it gets really warmed up it drops to 60 while idleing. It has a milodon oil pump with the adjustable pressure screw. I have it backed out almost all the way. It has a 7qrt. oil pan fully ported 440 source heads 586 lift comp. cam and a 950 dp holley. I am afraid once I start driving this thing and get on it some the oil will push past the critical parts and destroy my motor. What say ye
