I run 23 psi with no heater. I have an aluminum radiator that can stand that kind of pressure, but it would probably open a seam on a brass copper stock style radiator or the same brass and copper heater core. Higher pressure combats hot spots (steam bubbles) from forming in your block which is a consideration with a Siamesed bore BBC or a stock SBC 400 block.
