Start where you are. Were the 110's even original? Often times larger jets may not be needed. Wanted? yes, but may be extra work for nothing. The larger vacuum created by the larger volume may be able to pull more fuel through the existing jets. Changing the mains after the fact is a minor procedure without removing the carbs. It's adjusting the needle that gets more difficult. If you just have to play then MAYBE raise the needles by reinstalling the clips in the next lower notch before reinstalling the carbs. Then, if you need, you could also change mains afterwards. Don't over carb the engine! You haven't done much to it. Plus you didn't say you installed a better cam which, IMO, MIGHT necessitate more carb attention than a bump in displacement if that were the case.
