I'm still not sure what broke the chain
I am sure that the cam lobe wear is the same as many have been experiencing for the past few months. it is a comp cams core and was installed July 2013. I think mine lasted longer than other folks though and to be honest, I did not notice any loss of power so they were not worn as bad as some.
I had myself convinced that the cam was stuck because the chain was still on the cam gear and I couldn't move the cam by hand. I guess the spring tension and bent valves were too much for me to rotate the cam. I will go back with the katech c5r chain this time.

Just reading this and had some thought. They chain may have broken from too much tension or because it caught one of the sprocket teeth. How do they look?
The cam and lifters, at first glance look like oil starvation, but after reading your build, I see that you had a oil pump. The only thing I can think of is that the rockers were over-torqued putting too much pressure on the pushrods.
