i would go 84 or 84.5 and leave some room to refinish them later incase of fucking the walls up
 
look into that darton MID kit..from what i was reading about it last night it sounds pretty good. www.raceeng.com sells it for 499. Im gonna put it in this winter.

You can go to 86 or even 86.5 if you're adventurous, but I wouldn't boost anything larger than 85 just in case.
