exhaust cam position

[goatkeeper]

When pulling the head off my volvo v50 today I lost the position of the exhaust cam. I took the sprocket off to get timing belt out of way. Than I pulled the head off without putting the sprocket back on.

How do I figure out which way it goes. I can't find any kind of marking on the cam, only on the sprocket. There are three different ways for it to go, because there three bolts that hold on the sprocket.

Does anyone have a exhaust cam for a 2.4i that they can look at?

Thanks, Joseph
