I just made an overlay of both decks, and it appears that:
1. the 8 bolts in the row on the left (port) side are very close, if not the same
2. you have to add 2 bolts between rocker stands 1 & 2 and 5 & 6
3. the existing 15-bolt stand bolt between 3 & 4 is off quite a bit
4. there's a bolt missing midway along the pushrod side
5. there may be other errors on the pushrod side, but the other 6 bolts are pretty close
If you have P/Shop, e-mail me and I'll send you a .psd, you can slide the opacity control for the top layer to watch the bolt holes change.
