You don't need a 60 degree bed for PLA - that heat is just making the overhang curling worse. Try reducing to 40 degrees and see if you notice any improvement. You want as much cooling as possible with PLA, particularly on the overhangs. You didn't mention what your extruder temperature was, but again if you can reduce the temp by 5 or 10 degrees, that coupled with the lower-temp bed will help those overhanging layers, and they should curl less.
