Thanks to all. I have been driving Model A's on and off for 60 years, and never heard one boil inside the engine when it shut down when it still had water. It is not because my hearing is better now. Maybe it was because I had too many other things to do when I was 16 and did not stand and listen. Also, I never had a thermometer in the goose neck before, so did not see the water temperature rise when it was shut down.

The engine is running too hot so I will experiment with the GAV and the spark advance to see if that helps. Will also back flush engine block and radiator separately with a garden hose until the water is clear. I will also switch to antifreeze to get a higher boiling point mixture. I will keep you posted on results.
