will f-body lt headers work?

That's a sweet link. He did an awesome job with that truck, but he's using stock manifolds. Does anyone know if aftermarket shorties or mids will work from f-body or newer truck?

not quite the same but I have a set of shorties in a 88 k5- pick ups changed in 88 but not k5. They are off of a 02 avalanche (sp) found them in a bone yard.
they fit the frame I had to heavily mod the factory y pipe. mostly cut it to pieces but I have a 4x4 and t case is on the right.
They are getting rusty and i want to change them to long tube but cant find any. I am sure that some have to fit. I started a thread looking for me in the mechanical section. How about a vett, or them down under guys. Maybe some holden headers will fit. I looked at altering a set of big block chevy headers, the spacing was a bit too far off. any body do a gasket match to a ford or dodge exhaust manifold, how far off are the centers?
