Default Re: "B" on top of Model A Ford cylinder head

Ford came out with a high compression head for the Model A. Originally it was sold to police departments and became known as a Police Head. Later it was released to the general public. In order to identify it the letter B was placed on top of the head. Over the years this has caused a lot of confusion as in 1932 when the Model B was released (and through 1934) the heads had a letter C on them.
