I just came from my Model A club meeting, and got two completely opposite opinions on buying a higher compression head. I was advised against it by two fellows, since I have a babbitt engine. They both independently told me that the higher forces would crystalize the babbitt and destroy it.
Two other guys told me the opposite. They said (and rightfully so?), that the police head (5.3:1)was used successfully with babbit for years with no problems. A fifth guy said that there have been high compression race cars with babbitt, and no big issue.

I realize people have had different experiences, or heard/read different stuff about this, so I respect ALL INPUT. "There's wisdom in a multitude of council" - (the old black book)... So I invite any input here. Thanx in advance... Chuck
