I just bought some Hooker full length headers from Summit Racing today, they come with gaskets but not sure if they are Good gaskets, i heard that the copper gaskets are the best but cant seem to find them (besides jegs which wants 130 for em)canany one point me in the right direction or if they sell a different material that is just as good. (i have a small block 350) summit sells aluminum ones but not sure how well that material works.

 

I've had good luck with Percy's Seal-4-Good gaskets. They're a soft aluminum, laminated and compressible gasket. You can get them from Summit, and Auto Zone even carries them.
