You said you don't hear anything hitting while you crank the engine. Have you already replaced the chain? I would not expect cylinder damage, if anything there will be bent valves. The good news is that these engines come apart and go back together very well.
The thing to do is to check compression after replacing the chain. If the compression is okay, you'll be good to go. I don't know if these are interference engines, but I will be surprised if they are not.
How many miles on the car, and how often did you change oil?
Best of luck,
