Yes its looking very much like the valve timing has slipped for some reason, most likely a slack timing chain and you should be able to see this when the cam cover is removed. I think you'll also see that one or more valves will be stuck down ie not returning to their fully closed position. However if youre lucky and this hasnt happened you might be able to reset the cams to their correct positions and get the chain properly tensioned without removing the head. Note with care the cam cover rubber gasket can be reused if separated without tearing...
