    How to identify a LS6 intake?

    Quick question. Tomorrow I'm meeting a guy to buy his LS6 intake and I want to know how can I tell if an intake is a LS6 intake and not a LS1?

    Any specific part # or something that lets you know it's a LS6 intake. Pic would help

    Thx ahead of time

    the ls6 intake manifold will have a rounded bottom instead of a flat one like the ls1. there will also be no egr provision on the neck of the ls6 like it is on the ls1.

    also there will be a number stamped onto the side of the intake...here are the numbers

    Stock 2001-2002 F-body LS6 is 12561184.

    The Z06 LS6 is 12573572.

    The old LS1 intake with the EGR setup is 12560688.

    Reading in that ling I saw that I need to shave the bottom so that it will fit on my 98? Also the link on how to install seems to have expired. Any body have some more directions?
