Hummm... I wouldn't think it's stock since my 2000 SS has the EGR. Best I can offer is to look at a pic of an LS6 intake and compare. Sorry, I can't help much more.

Pic won't help too much...besides the egr tube the ls1 and ls6 manifold are close to identical from the top....you have to look at the bottom to see the diff.

You're gonna have trouble passing emissions here in cali without a egr...but maybe you'll get lucky and they won't notice.
