Moved the thread for you.
Compression will vary based on mileage, valve wear, piston ring condition, Ect.
Normally each cylinder should be within a certain percent of each other. With that being said, a service manual will tell you complete specifications on what they should be and what percent within one another. Low compression or big differences between each will mean a rebuild
