They look consistent, which is the important thing.

Being consistent is important to knowing if anything is wrong with a particular cylinder. If they are low overall, it means that the engine is worn. I don't know the spec, you will have to look it up in an FSM.

138 is the bottom of normal on a warm engine, but there are so many variables. A cold engine at high altitude would high much lower numbers.
