Disclaimer: I am no expert, hopefully someone with more experience will chime in. However, if it was my car, I would not start it again. First I'd pull the rubber plugs and check the timing of the four cams as described in Wayne's article. Assuming it is off, then I would do a leakdown test after the cams are timed, to make sure none of the valves are bent.

I think the 2 tensioners are different. Is it possible they were reversed, perhaps causing a jump of chain?
