    I believe at some point you bent a valve my friend. So just go ahead and pull the head off and you will find your problem.

    Something is allowing the compression to escape. So valves, rings, gaskets, cam, cam gear. I'd say make sure your piston is moving up and down but I believe you would have already checked that. Also if you have the head off flip it over and fill it with break clean on the valve side and make sure it doesn't drain out when they are closed.
