Highest Reliable Compression Ratio
I want to hear from those who are running 6:1 and 7:1 compression heads on Model "A" and Model "B" engines with babbitt bearings, and stock oiling systems.
Can 6:1 and 7:1 compression ratio heads be run reliably for cars that do a lot of touring? If any, what issues have you experienced?
