Wow must be nice. Since you are tracking your car at FC and concerned about higher octane fuel, I am assuming you have taken care of other essentials already?

pads, fluid, wash, wax, fuel are my essentials

Any chance of harming the exhaust valves due to the longer burn of the higher octane fuel? XViper?

It depends on how the octane was raised to those higher levels. If it's done by use of ethanol, then long term use may have some consequences on injector life and cleanliness. As valves and such, they may get more deposits on them quicker, but on the most part, I don't think using a higher octane fuel is going to "hurt" the engine significantly in the short term. Can't say for long term. I don't think there's any documentation on this of anyone using that kind of octane all the time in an 11:1 engine except perhaps in race cars and we all know they don't last long without rebuilds.
