You can try and remove the valve cover and see if you can see the chain loose. Thats what I would do first I have seen the valve guides even get split from the pistons hitting the valves. Lets see what we find with removing the valve cover. Worse case senerio you need a head and timming chain set. Let me know what you find and we will go from there.
