Haven't pulled the heads yet...stay tuned.

Check your timing belt tensioner. I bet it's broken. Skipped timing and the rest is the result. Poston hits tdc while piston is full open and the rest is obvious.
Was talking to GTAHVIT and it's a known issue. (known as in owners. Not GM)
Hard to say wether the tensioner breaks and creates the chain result or the chain result breaks the tensioner. But some tensioners have been found missing or broken without an engine failure.
