Yes this is good. The LS6 makes more power and has no egr. If you look at the intake, right behind the throttle body, it will either be smooth or it will have some emissions stuff (egr?). If it is smooth it's an LS6.

You definately have the LS6 intake. Like previously mentioned, they came standard in every 2001 & 2002 F-body. As for the ls6 block I'm not sure how to tell if you have it.
But I wouldn't go looking for it either. It'll gain you nothing power wise and by the time a stronger block is needed you've all ready replaced it with a 402, 408 or 427 anyway

Re: LS6 Intake Manifold on late 2002's
Here's an article on teh development of the LS6, most of the improvements to the LS1 came as a result of common parts developed for the LS6. Here's how to tell if you've got an 'LS6' block, these became the standard block for LS1 and LS6 in 2003, but were fed in gradually from late '01 and appeared in LS1 builds I guess as overspill. Nice to have, but not worth getting if you don't. I found a quote from John Juriga a few years ago saying that the reduction in parasitic loss was worth a couple of hp, but the change was made mostly to avoid oil whipping and starvation from failure to flow back. Can't find it now.

Negative. The 02's and 01's were identical for LS6 intake and 78MM throttle body.
Here is a real good breakdown of the differences between the years:

honestly they are nearly identical
the later years got the intake, but a smaller cam
but how could you leave it stock??
j/k
even basic bolt ons will have them equal in the end, and even more so if you dive into the motor
