Sorry mate, your post got held up in the moderation queue as it contained a link to an image in another forum. I've approved this for you.

What does a leakdown test show? It does sound like the head. Is the gasket ok?

sounds like the head has gone and might have a crack in it whip the head off and have a look but also start looking round for another head as well
