Durango headers?

As it seems like the Durango manifolds fit the early As pretty easily I was wondering if anyone had tried Durango shorty headers? There are a bunch of them for sale on ebay that look like they may work but it's difficult to tell without having a set in front of you. Does anyone have any information?

Failing that, about how much should I pay for manifolds and does anyone have a good source for them? I've not seen any in the junkyards round here.
