Do a search - here's a couple on the first page of "flathead early heads": http://www.jalopyjournal.com/forum/showthread.php?t=225221 http://www.jalopyjournal.com/forum/showthread.php?t=223962 http://www.jalopyjournal.com/forum/showthread.php?t=215174
The heads will interchange but there is a concern about some water passages. There are books available that mention the necessary mods. I believe you will want to use the gaskets for the particular heads. The water passages in question will need to be plugged. The Bishop/Tardel book mentions it and thats the one that comes to mind anyway and I'm sure others do also. I hope that helps.
