99 headers fit an 02?

Will headers off of a 99 ls1 fit an 02 ls1? I am wondering this because i see seperate part numbers on some sites for these headers. What is the difference?

In particular, tpis headers.

Re: 99 headers fit an 02?

you will need to block off the egr port on the 99 headers, plus you will need to rotate the air tube flanges 90 degrees to mate up to the later '01-'02 model.
