400 headers @&^#

Thanks for the replies.

Yes, they are manifolds. My mistake in calling them headers, I am still trying to get them off now, one bolt in the far back if your standing at the hood...I cant see how to get it out without removing the steering linkage..and not real sure how that comes off. I did take the bolts off from inside thinking that would give me enough wiggle room but doesnt have appeared to worked.

Oh, and I didnt cut the pipe. Thats what I found when I removed the clamp...
