Well, in theory, your mods shouldn't change too much, but with any modification to the motor, including overboring 1 size, you will need to take it easy through break-in and check your plugs. Obviously, after a fresh top end, you can't go right out and run a WOT test, but fire it up and run around, after you've checked your "after top end" compression, and check your plugs to make sure they're plenty colored. Once break-in is complete, go ahead and do a wot jet check and make sure your jetting still matches your setup, you might have a little variance and then you may not have any. Regardless, it shouldn't be much at all, if anything.
