Ah. Yep, unfortunately, that plug can be pushed against the camshaft... Noticed that could happen when I assembled the 478. My Dad told me, that must have caused problems somewhere in the past...

As for a cam keeper/plate, hopefully, one of the forum members has a core engine that they are willing to part out. I would recommend posting a request in the Marketplace here on the forum.

Did you find out if the oil drain hole in the camshaft was plugged with junk?
