4x4 Headers??

[Blazerowner]

I bought a set of Dougs 372Y headers and sure enough they don't fit even though they say they are for a 4wd. The passenger side collector was dumping right on the rear shackle bolt for the spring. I called them and they were unaware of the issue even though I found several sites where people with a 69-72 4wd have had this issue and even called them for help. The options used were to use a huge bar to try and move the collector or cut it off and re-weld it. I have no desire to do either so back they go. My question is what are others running on their 4wd? I am thinking of getting some mid length or shorty style. I have heard the Sanderson headers can leak on an aluminum head which is what I am running so I wont go with them. I'm trying not to spend a small fortune but willing to spend up to 700 for a nice set.
