New Top End

Bought a bike from a kid that brew it up likely by overheating as he was stuck in a mud hole and tried reving his way out of it. I have the head and cylinder apart, and the rings were stuck and there is scoring on the piston and cylinder wall. Heavy carbon deposits are on the head and piston. Lower end rotates smoothly and does not show any signs of freeplay.

Question is, I want to replace the cylinder and piston with new OEM parts, and was wondering if they will already be a good fit, or whether the cylinder will need boring and/or honing to get the fit within tolerances. If that latter is the case, then would it be better to just oversize the existing cylinder bore and go with an oversized piston?

Help is much appreciated.
