All the bolts line up, but the threads for the two bolts on the cam chain side are on the cylinder for the 06 version, with threads on the 05 head. So I just dont run any bolts there, no problems with leakage so its all good !
I also seem to remember chamfering the other side to clear the cases, but only by a couple of mill.
The water pump transfer is also machined shallower on the 06 cylinder, so I machined a new shorter o ring sleeve to suit.
