Bought a used head that was supposed to be from another 97. Took it to a machine shop and now theyre telling me that the cap/bolts that hold down the cams are different than my original head has. My head had these things sticking out of the head that the cam caps screwed into. They suggested that I not use this head becuae there could be other differences.

My head is the one with the cams in it in the pics
