Thanks for the info, I was digging around my stash and found a 7028271 XP 2637 carb. 9/20/1967
WOW how lucky is that!
I have only heard Firebird 400 HO had #16 heads. Not sure about the #216 head but Wallace Racing does list a 16/216 for 68. I would have thought F 27 7 Jun 27 67 would be for a 67 dated head but Wallace Racing shows as 68 16/216 head. I would like to hear from others about this and details about the #216.
Here is a couple of photos of my engine dressed out according to my research and should be pretty correct.
