    Question 99 Manifold to 01 Header Swap Gaskets

    I picked up a 2001 header, recently. All I still need is the gaskets, and then I can do the swap. The gasket between the head and the manifold/header is listed as the same for both the 99 manifold and 01 header, so no problem there. The gasket between the header/manifold and exhaust pipe is listed differently for the '99 (http://www.oreillyauto.com/site/c/de...L0/EG24921.oap) and '01 (http://www.oreillyauto.com/site/c/detail/FEL0/61327.oap) on the O'reilly site, which confuses me a bit. It doesn't look like the bolt holes on the gaskets are in the same place, which would mean that the swap isn't as drop-in as I originally thought.

    Am I looking at the wrong gasket(s)?

    Thanks

    Bolt holes look the same to me why not go to O'reilly and look at them both and compare them.

    The 01 gasket has all three holes equidistant, the 99 has different spacing between one pair, judging from the picture. That is what is confusing me.

    Good idea - I'll take the new manifold and see which fits.
