congrats on the bird purchase (my fav year but I'm prejudice that way

)
your pics shows up but you'll have to be more specific with ?'s
I wouldn't be to overly nervous about the rebuilt engine.
The forum can help you check #'s on the heads and block and get it up and running. Unless you're are going for a 300 pt concours resto chances are the engine you have is going to be OK. It just depends on what you want it be for the money you spent.
You can search and find several suggestions about how to get one checked and ready to start up after sitting like that. If you can't we can help you thru it.
