I remebered doing a compression test revealing that cyl#1 was 110psi and cyl#4 was 140 psi....that seems low. I have almost always had a rough idle and maybe my cams just aplified it to the point to read a misfire. It might be possible that I need a valve job although I will be replacing with port&polished heads. Thoughts??

110 and 140 are low, thought the range was 160-200psi. Its in the Bentley for sure...
