    Exhaust Manifold Gaskets

    I' m installing Mac's on my girlfriends 99z and need the part number's for GM's exhaust manifold gaskets (to head) and 3 smaller gaskets for emissions hook up. I want to purchase on GMPartdirect.com. The local GM dealer is closed so I can't call an ask. Is there a link to common part numbers for an LS1 on this site anywhere?

    Thanks in advance.

    exhaust manifold gasket - 12600530 comes as 1 need to order a pair
    AIR gaskets - 12553617 comes in a pack of 6
    EGR gasket - 12553047 come single

    Speed inc sells the gaskets pretty cheap on their site. $20 for the pair of header gaskets and $2 for a pair of AIR gaskets. The EGR one I don't remember but it's cheaper than the dealer who charged me $13 for one.
