Pete,try not to confuse static compression and dynamic compression ratio's.

Generally speaking most guys are making real nice power with 98 unleaded without issue. My own engine made no more power on the dyno when using dedicated 100 octane racing gas vs 98 RON unleaded.
There is only one way to find out ,and that is give it a whirl.Chances are it will be ok.If it does not tolerate that fuel you will know.
