Oil pressure

(1990 Chevrolet Camaro)
in Casper, WY on March 17, 2018
i have a 421 sbc that was worked through. i have replace mains and rod bearings. after i primed the pump i started the motor up and have 20 psi of oil pressure when cold and 7-8 psi when hot. if the oil gallies were opened up a bunch would that drop my oil pressure? is it ok to un with that kind of pressure on the street? Do i need to replace my high volume with a high pressure pump?
