The photo of the valley pan reminds me of my cousin. Probably around 1977 or so he had a 69 RR that he blew up a bunch of 383's in. He had bought a junk yard 383 and put it in the car. We couldnt get it to start and he was turning the distributor as I was cranking it. The engine popped, blew the valley pan up and almost blew the valve covers off, they were junk after that LOL.

R.I.P. Wade, I miss you buddy.
