Not Ranked
I am not 100% familiar how MON and RON convert. I had a 12,5:1 454 (LS-7) once in my car in Germany and we have 98 RON. If your gearing is short and the cam matches the CR you should be able to drive your car.
Listen for pinging at part throttle, but even more important at full throttle (WOT). WOT rarely applies in the US, but on German highways you may find yourself going 160 mph in no time.
I realized that one can hear pinging better, especially with sidepipes, if you wear ear plugs.
Better even, go on a chassis dyno, adjust the timing properly. Retard 3 more degrees for the street, or whatever the dyno operator suggest.
This is a very sensitive topic and as you know too much timing can kill your motor in 10 seconds.
