Thanks for the insight oldman.
Yes, best thing is to ask around people running this setup for a while. Assuming GM is comfortable with ~ 10 PSI on an engine with 1 point lower C/R and with forged material, then my guess for a "safe" boost on a 1 point higher C/R with non-forged material should be ~ 7-8 (Max.) PSI - and yes, no less than 100K reasonable use (not "beating on her") miles longevity is the target.
