The only time I'd suggest running over 12:1 on a daily driver is if you have a seperate race gas tune that you will run. Otherwise what is the point of running 13:1 compression if you are going to have to pull timing and detune it to run on 93 octane. You will make just as much power running 11.5:1 and decent tune.
but with a tankfull of 110+ octane and the race gas tune, you'll have another 10-20whp to play with. I think thats worth the extra work.
