2G AC tensioner pulley for swap?

[WytChoclitJ]

When doing a 1g block/2g head swap do you use the 1g or the 2g ac tensioner pulley?

I would imagine that the distance between cams on the head's are the same. But if your using a 1g block use a 1g belt, and if using a 2g block a 2g belt. As the AC belt only runs off pulleys from the block not the head.

You have to use the 6 bolt tensioner because everything for that is on the block its self. Unless you could switch the AC bracket to a 2g and then use that tensioner. BUT they might be the same?
