Zone points?

[Alogon]

What I am trying to do is edit the swampofnohope and dreadlands so that they connect to each other threw the burring woods, and field of bone zones. I got this to work just fine my only problem is when you go threw one zone you pop up in the other facing the zone. This is because both of these zone lines are on the north side of their zone (according to eqatlas maps). I have tried to set the target_heading for these zones and had no luck, can someone please explain to me how the target_heading works, or what I need to be doing so that when you zone threw either way you will come out heading 130 (according to #loc)?
