You performed a dry test. A wet test would be squirting a tablespoon of oil into the CC thru the sparkplug holes. Retest. If the pressure goes higher than your dry readings you can usually pinpoint the rings being the culprit.
However, since your readings are within spec there really is no need for wet compression test.

Rings, valve guides and valve seals will cause oil burning nothing to do with the condition of your engines bearings. You can easily upgrade to better heads and parts but in the end you still have a 100K+ mile shortblock. I would perform a leakdown test to see the real condition of the motor.

Great info, thanks for clearing things up a bit.

Theyre not all that low, but more importantly, theyre a pretty close grouping. Good to hear.

Excellent compression readings, all reading are within 8% of each other which is plenty acceptable.
