Thanks, the whole cam didn't shift, the camshaft timing gear assembly actually came apart, the area circled had popped out, in the photo I had already "repaired" it. However you are right, looks like I need a whole new gear assembly, so that's cam out.
Yeah the valve cover is stuffed, I'll need a new one and I'll need some way to check if the same has happened in the rear bank. At this point I'm just tempted to seek out a good wrecker motor, this thing hasn't been looked after at all.
