Hey man, i know this is from your post along time ago, but in this pic you say the egr valve. Last night doing my install i noticed i had a leak also and thought that this big plate right off the back of the head was the egr valve. When i pulled the bolts out antifreeze came gushing out. Do you or anyone else know what the hell this plate with the bolts is and if i screwed anything up by breaking the seal??

That black plate with the tube in it transfers coolant from one water port on the head to another one. I don't think you screwed anything up by taking it off. It might have a metal gasket on it and reusing it would be fine as long as you didn't bend it up taking it off. You could use a small bead of RTV to seal it up if need be.
