Re: Tapped Steam Hole Plug Size Model B block
The issue down the road you are trying to avoid is that if you run a stock Model A head on a Model B block the holes will be too close to the edge of the gasket due to the shape of the combustion chamber and will probably leak. If you run a Model a Police head, a Model B head, or one of the aftermarket high compression heads that I have seen there is no problem and you can forget about closing the holes. I don't think I would ever build an engine and use a stock Model A head.
