You definitely need a new camshaft. :(

Have you pulled off the cylinder head? I wonder if the piston hit the valves? If you choose to repair this engine you will need to remove the metal fragments which fell down the cam chain passage into the area around the flywheel. You will also need to get a slide hammer to remove the damaged camshaft. If you want to get an idea of some of the work involved, you might enjoy reading the following thread.
