Piston Size

I am into my engine and am having trouble finding engine specs. Does anyone have the cylinder bore size on a 2005 4.0 engine? I have checked and it shows 3.740" or 95.0 mm but the information I have accessed shows it should be 95.5 mm. The piston has D 05 EA2 and RC 72 stamped on top. Want to order parts and be sure my motor has or has not had work done to it in the past.

Photo of piston, and the damage was found because of a head gasket issue when we pulled the heads. Motor ran fine and no excess oil consumption.
