I just was wondering if anyone new what kind of boost can be run on stock head studs, I had a local shop tell me the head likes to twist off at anything more than ten pounds, and to o ring the block for larger studs. I would like to try to avoid that bein that my budget is getting low. I was kind of hoping to just run arp head studs to solve some of the problem. Hoping to be able to tune from 12 to fifteen pounds on 116 octane race gas. Running stock internals, and an eagle block gaurd. The car will have bigger injectors, afc II, fmu, and a check valve on the map sensor. Just wondering what someone else might have gotten by on for boost. Thanks.
