It's interesting about the SS seats. I recall all the talk back when lead was taken out of the gasoline in '75, how antique cars would suffer from valve seat failure, and a lot of people were scrambling to have hardened seats installed.

Fast forward to today, and we find that is not the case. The original design was/is fine, and actually looks like it's better to stay stock as the way Ford designed this engine.

The low comp. ratio of the Model A seems to be pretty forgiving. Maybe that is one reason Henry worked it out that way.

30Tudor keep us informed on your situation.
