they have different ports.
"Exhaust ports are different with LS6 heads. LS1 exhaust ports have an "Oval" shape. The LS6 exhaust port is " D " shaped."
google is your friend.

Yes, pm me or look at the thread I posted last fall...
http://forums.corvetteforum.com/c5-t...went-well.html
The LT headers, cats and catback i have came off an 03 Z06.
You will have to install the following:
Oil dipstick and tube from an 03 C5
Passenger side AIR pipe from an 03 C5

as long as the header is oval not d shaped they will still work on the dshape port the dshape will not work with the oval ports since it wont compleatly cover the ports but if im not mistaken even headers for the ls6 heads come rounded since they will over lap and still seal to the head. jut my 2 cents i dont have the same experance with vettes as most on this form so my logic could be wrong. lol

my answer did not have "no" in it.
the google reference was to look up all the available c5 headers and he would see that they usually were made for ls1 and ls6.

i got this link by asking "c5 headers".

This is due to the difference in the dipstick tube mounting point and the passenger side AIR tubes.
His exact question was WOULD it fit his car and the answer "without google" is yes.

but isnt the post about headers? neither car comes stock with headers so the stock manifolds would happen to be engine specific, but headers are aftermarket and shouldnt interfear with the oil dip stick. reember manifolds are what come stock on an engine there usualy 2 pieces and make of cast iron and dont flow as well where as headers are stanless steel one solid piece and designed for maxumam exhaust flow, so was the op refering to manifolds or headers?

There was a change around 2001 when the dipstick went from being mounted to the exhaust manifold (like my 99 was) to the front of the passenger side header. The AIR system position changed also from back of the exhaust manifold to the center of the manifold/header.
Other than that the headers bolt up and work fine. You just have to get the round port LS1 header gaskets instead of the "D" port header gaskets the LS6 used.

lt and shorties are both headers not manifolds as far as headers go normals neither interfere with the oil dip skitck if it a 99 u will need the tube off a newer vette but most lts by pass the air system where as shortys incorperate it shorties u have to get the aproprate one or the tube wont line up but if LTS the system get bypassed ive not seen any with the flang built in. now with manifolds (cast iron came stock on the care) they tend to be engine specific and with in ceritin years as little changes over the years to the engines design effect weather or not they fit. the bigest thign to relise is
Headers = aftermarket (stanless steel)
Manifolds = Stock OEM came with a vechicel from the manafucture (made of cast iron)

My TPIS headers have the correct AIR tubing and are not bypassed.
You are right, a lot of the headers either block off the AIR connections or don't even have them.

ok i havent seen em with the flang my bad on that but with shorties u can get a flang welded on to the pipe so they can be put on diffrent cars it takes a little fabricationg. for example on my 99 when i boughts it it had headers for a newer vette so the air tube didnt line up so i block off plate was intalled. but the hpipe was welded with a flng to make them fit

If the entire exhaust were being changed out, it would fit perfectly, if you take a part from a newer C5 (01+) and put it on our 99's you will have to modify to make it fit, but it will work.

Perfect example: you wrote in the recent Who's owned a C5 and an S2000 thread that a Miata is a disguised 323.
Then when confronted you pulled up most likely some wikipedia quote about the Mazba B engine. So you think the Miata is a disguised 323 due to the same engine. I guess my Vette is a disguised Silverado, or an Express Van.
Thank you, you Google/Wikipedia God
