140 is as low as I would like so the 130 is a worry and no more than 10% between cylinders you are around 15% between highest and lowest.
Really should have done a wet test with a squirt of oil in each cylinder to see what they bounce up to as that would give you more of an idea if it is a bore & piston problem or a valve & head problem.
But it also can depend on how accurate your gauge is and a number of other factors but I wouldn't be pulling anything apert based just on that one test without doing a follow up wet test.
