Check with your local auto parts store, engine parts are still available for the flatheads, although they may be special order. Have a look here:

They used to have some parts for them.

Also, go to to a magazine store and pick up a copy of HEMMINGS MOTOR NEWS. This is a monthly publication that has ads for parts and commercial parts suppliers. You should find what you need through there.
