double hump.....question!? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I went and dug out my double humps (three or four sets) and I noticed one set has a Z/2. cast into the intake runners (the center pair looking from the valve side). I have seen literally hundreds of these heads and I have not ever seen this marking, so the question is, are these from the Z/28? They are date coded on 67 and on MORTEC's site they say to be from the 302/327, so is this a super rare $1,000 set of heads or did some come with the stamping that has nothing to do with the model of car they fit? Curious, I am not guaging a value, moreover I am trying to ID these heads. I have done a search on ebay and mortec with no luck? Any SBC head guru's out there?
