    I think year 2000 didn't have the egr port, at least mine didn't have the port on the top.

    If you buy one off a 97-2000 vette they do not have the egr hole, all 98-00 f-body's have the egr hole.

    C5Z28 is correct, the Vettes had the LS1 intake with no EGR port.

    1998, 99, and 2000 fbodies came from the factory with the LS1 intake with an EGR.

    There was more than one part # but that is an LS6. Another # is 12561184. Also if the bottom is flat you know it is an LS6

    EDIT: Found this....... ....http://www.c5help.com/partnumbers.htm
