I think it's pretty common to see a lot of mixing and matching of flathead engine components on an engine. I also agree with BarnJunk. Pull the heads and see what you find. That will tell us a lot more. I always like opening one of these engines up. It's like unwrapping a present or opening a time capsule. You get to see the size of the bore, if the pistons and valves have ever been replaced and the condition of the cylinder walls tell you a lot about the engines life.
