Yeah after I posted I say how the dside collector is and O2 sensor placement. I had to cut that "ear" of the bellhousing on the pside to clear my pacesetters. They may be an option for you 2wd guys. 67ss509 is suppose to be getting me some pics of his kooks on his truck in a week or two. They are 1 7/8. I just cant see you need that big of a header, 1 7/8 should be plenty. But then again why not if you are upgrading and you wont miss in tq lost down low with that radix.

They fit but they also hit the frame. With a little work they go on but it is close.
