One of my friends use to work for a big engine rebuilder back in the day. I forget which one. He told me that all the core engines got disassembled and the stuff went in piles. Heads in one pile, block in a other pile, and so on for a certain engine type. They rebuilt the engines using parts out of the piles. You got what you got, an engine that runs.
