So no go on either ones i have ?
GTOs wont fit. Maybe one side of the truck ones.

F bodys and vettes manifolds have been proven to work. I would shoot for either of these or LS gbody swp headers.
Ive been looking into this for the past few weeks myself and when time comes, I think Ill just be going with ceramic Hedmen swap headers.

Well, I just came across another thread on this board where a member says he used GTO LS2 manifolds on his swap with 1" set backs.

Everything else Ive read said they would not/do not fit. Something about a wierd angle IIRC. I passed on a cheap set myself because it was my understanding they wouldnt work.
Maybe you could pm the member and get more info. His name is "maven" on this board and the thread is called"LS Swap parts what works and what doesnt". Please update with whatever info you get.

If they do in fact work, I myself would love to see pictures showing the angle.
And I apoligize for any mis information.

If you already have them, then just try them. I'm sure several people are interested in the results.
