I ran arp bolts to 23 psi with no problems. If you have a "push water" tune up, there isn't going to be much difference in bolts or studs. Don't get me wrong, the studs are better, but a pump gas street car should be fine under 20 psi on bolts. If I remember, there is a significant price increase with the studs huh?
