If the studs are straight then 11/16 will be clearance for 5/8 studs. If the studs aren't perfect then you might have to open one or two holes up a touch more. 0.060 clearance on a stud is a lot. If that doesn't clear then your studs are not in there very straight. If that is the case then you'll have issues with the wheel also. Better to solve the root problem than to hog everything out......
