I didn't see in your list what brand the timing chain set was. This may not be the issue either but I bought a Cloyes double roller set and the bottom sprocket or crank sprocket was made incorrectly. The chain did not seat in the sprocket properly. I was able to send it back and get it replaced and was told that they had several like that. (I bought it from Summit). Anyway, I don't know if you could have even assembled it like it was but if you did I imagine it would have failed pretty quickly.
Also it's hard to tell from the photos but the chain appears to be behind the cam sprocket. Are you able to move the cam in and out? Maybe they forgot to put the plate that holds the cam in the block and the cam walked...
Like Scotty says, it's pretty hard to break a double roller.
