Bent pushrods :-(

Last night I started the job to take the cylinder head off. I got everything off exept the actual head before it got too dark, have to continue another day. When I took the rocker cover off discovered that one pushrod was broken and a couple of the others bent. My guess is that the head gasket broke and the engine hydrolocked, but I will know more when the head comes off.

The pushrods, except the broken one which I forgot to bring home for the photo:
