Mark I think that there is some safety at higher RPM as you suggest. But I believe that the RPM the engine is most likely to detonate at is the peak torque RPM. It sounds like with your combination you might be able to have CR of about 9.8 at normal deck heights. I'm no expert on ignition curves for these engines but you could probably start with the standard 2.2 "s" curve.
