Many years ago I ran a Model A cylinder head on a Model B engine in my 1929 Station Wagon with oversize tires for hard driving on sandy beaches. At the time my nephew was a hot rodder and he threaded bolts into the two steam holes that are in the block, then cut and filed them flat. Used the regular Model A cylinder head gasket, drove many miles over about 12 years, never had a problem.
