is there a way to tell if you will have to re-bore with the head on still? like with a boroscope down the spark plug hole? i have low compression, front of car to back its 115, 110, 110, 105 (105 closest to firewall) did a compression test at two shops and got the same numbers so i don't think that it's an error in the test. would be nice though if it was...
i'm hoping to be able to hone and not have to bore, but who knows.
