0psi? are you sure? that sounds wrong, even a bad set of rings will get you 60-90psi of compression. Even if half the top of the piston is missing/melted you should still get something. Do more testing. pull the head if you have to.
Did you get the block decked at any point and forget to deck the oil pump? Was anyone ever in the bottom end? pull the valvecover and watch the valves open and close, and check the cam timing.
***edit
I watched your video. The only extra thing I can think of is improper torque sequence of head studs, which you shouldnt even be using unless you decked the block with a torque plate attached.
If I was in your situation, I would double check the compression first, and do a leakdown test, to verify where your compression is going. Buy one on ebay if you have to. I found one at harbor freight in a pinch, used and returned it.
