Ok I asked the other day about this. But can't find it to see if question was answered. So I'll ask again I'm in the process of pulling left head & I have gott all the bolts out of timing chain cover. Including the 4 out of the oil pan & it still feels like something is holding it I'm about to the point that I'm ready to just yank it off if breaks I'll just have to deal with that later so somebody please give me some help!!!
