If you are planning to tear into the engine you probably should identify which variation of Ford flathead V8 is in your car. If your engine is in good shape and runs decently I would leave well enough alone and enjoy what you have.
There are multiple versions that will work well, but take different parts. There is a thread here with a lot of information that can help you identify what you have:
