There tends to be more Airflow to the back two cylinders (#5 and #6) . They then run leaner and the rings are subject to more wear....and less compression. I would't concern myself with the differential in compression numbers. There are some good running zs with alot worse. Bytheway, just make one post about the same subject...posting more is just going to irritate people. You can go back and delete any post if no one has responded to it. Good luck, mark
