Will the full length 3rd gen hedman headers fit on an Lt1? I know there is a port difference but is it enough to be concerned about? Anyone currently running these on an Lt1 3rd gen??

I know the hedman shorty headers fit.Don't know if its any help.

 

I don't know about long tubes but I have slp 1 3/4 single cat headers for my car . They require an extra 02 bung welded into the pass side header as well as a egr ( I believe that is what it is ) port welded on for the flex pipe that goes to the back of the manifold.
I think that long tubes would be the same as long as the tubes were big enough to clear the big d shaped exhaust ports.
Hope this helps.

I have the Heddman shorty headers and they barely fit, I dont see anyway that long tube headers would fit
