Default low compression

hi all wonder if some one can advise on this. getting about 110 on the compression test, took the engine out, the pistons measure 79.42, ring gap is about 30 thou, the bore is about 0.4 oversize, would this affect the compression that much, the head looks good valves all seated nicely etc. any advice greatly appreciated.

Think anything under 120 Is bad news
