FWIW: One (1) experience:

Without a thorough examination, one never knows just by word of mouth what one will experience on the hidden inside of an engine when one buys a Model A or a Model A engine.

For example: I had one of my best of several original Model A cams re-ground about (20) years ago by a "highly recommended" young guy in a "highly recommended" mechanic shop, where this young guy said his precise computerized grinder could render an exact duplication of the function of a B cam.

Fortunately, I had measured all cam lobes "before" re-grinding with a dial micrometer and compared same to precise drawings mailed to me by Mr. Marco and Mr. Yapp.

Results: After re-measuring afterwards, so bad with unequal measurements from lobe to lobe, I later bought and installed a new 330 cam from Mr. Stipe which was "Right-On" on every lobe.

If anyone is interested in reading further about re-ground cams, the Ahooga Forum has many interesting discussions and experiences shared from a few years back in regards to A & B cams.
