Does this help? I got the photo from the interweb. It's a 390 though.
Do you mean the washer behind the timing gear bolt? That goes on with the bowl side toward the engine so it acts like a lock washer.
The thin round spring? I think you mean the oil slinger. It deflects the oil from trying to leak out the timing cover seal.
Make sure you grease up the timing cover seal (wheel bearing grease is fine) so it does not burn up without lubrication when you start the engine back up.
