This may not be the best deal I have ever made. Head off and this is what I found...
Every valve on bank 1 hit a piston judging from the marks on the pistons, all the exhaust valves are bent to the point where they will not close, and some of the intake valves.
The head is toast... note that the exhaust valve on the right broke and then the stem was driven into the head beside the valve guide. Ouch.
... and the engine will still not turn over so the other bank may be problematic also. Maybe the short block is salvageable???
