I run Valvoline VR1 straight 30w, it has ZDDP in it. My hot oil pressure is 25psi at idle and 50psi above 1,000rpm. I gave extra attention to the oil passages when building it, making sure everything was clean and making sure the top end got plenty of oil up to the rockers. Mine is a later higher pressure setup with the return line.
