I would not worry about your oil pressure or motor life........I have a 351-W,about 350 hp,iron heads,stock Melling oil pump...... I run 10/30 Mobil 1,cold start up,steady 60 psi,when my oil temp reaches 180 it idles at around 30 psi,anything over 2000 rpms,it runs 50 to 55 psi..... When running open track events,my oil temp has gone to 230,I don't like it but do not have an oil cooler (yet),usually runs 210 to 220 oil temp on the track,at that temp,idle oil pressure is around 20 psi,at speed,my oil pressure is around 45 to 50 psi,whether I'm running 2000 rpms or 5500 rpms..... Motor now has 21,000 miles on it...... It is either on the highway cruising or on the track...... As long as I have 20 psi or more at idle and 45 at speed I do not worry about it,it's been this way for three years now.....
I switched from Shell Rotella T 15-40 to Mobil 1 and actually "lost" about 5 psi across the board when hot,idle psi is the same.........
I would say just drive it,I would not worry about the oil pressures..........
