Gotta build ANOTHER engine.

If the pic of the timing set is how the motor was run...... the cam is advanced 2.5 teeth......... or about 35 degrees.
This was your problem.

Fix it all, correctly install the timing set next time, check cam timing, check v/p clearance.
35 degrees? yowzah!
I don't know what all valves hitting pistons can do, but I think I'd check that rotating assembly pretty close, especially the con rods because they can bend or twist. Of course, the pushrods, and all the remaining valves have to be checked for straightness, and running "true", also.
