i would suggest loosely installing the 110mm bottom bracket so that it is adjustable. then bolt the crank to bb. wind the bb in until there's 2mm between inner ring and chainstay, or 4mm between crank arm and chainstay, whichever's the critical dimension. then check where the centreline of the chainset is relative to the cassette, ideally should be aligned with centreline of cassette. wind the bb out if required to find this.
how much of the bb thread is left exposed? if 2-3mm this could be taken up by spacer washers placed between bb end shell and the frame (SJS sell these, among others). check that the non-drive side crank arm still clears the left hand chainstay. you will have a slight but not normally noticeable offset.
alternatively buy a bb with the additional length on both sides, which probably means going from 110 to 113 (1.5mm each side), 115 (2.5mm each side), or greater.
