Thanks to all who replied, you were all pretty much correct. A valve adjustment took care of the misfires and engine codes.

1989 Chevrolet C1500 Silverado 5.7L Cruise Control VIN: 1GTDC14K3K
I think it was just bad motors. It obviously was not a vacuum leak considering there isnt any vacuum. The wires all test good so I am pretty sure I just kept getting bad motors. The owner did not want to spend the money on a new motor so I cant say 100 percent...
