What kind of car do you intend to use them on? Engine, trans, steering type etc. As you can imagine my experience only goes so far with all of the possible part combinations.
If you want headers that fit really good there is no substitute for TTI.
I would think you should have no issues in a 70 E body. I have mocked them up and the z bar is clear of the tubes etc. Sounds like a very cool car! If you want any pics of the headers bolted to an engine I have a big block in the shop on a stand.
