There are only two valve cover gaskets for the entire series of that engine. Fel-Pro VS10604 fits the early style with two studs through the top of the cover. This would be 215 and 223 through 1959. Fel-Pro VS12690 fits the 8 bolt valve cover used from 1960 on in 223 and 262 engines.
You did not mention whether you wanted the front or rear crankshaft seal but the rear seal is Fel-Pro BS61413 (C1AZ6A321A, C1AZ6A32A) and the same for 223 and 262.
All the above parts are currently available from Rock Auto. I'd imagine your local NAPA should have them as well.
Bubba's information and request for pictures, etc. will help us identify what you have for the future.
