Default Header install - need new gaskets?

I'm getting ready to install headers on my '98 convertible with 41K miles. Can I re-use the head and mid-pipe flange gaskets or should I plan on getting new ones? Same question on the small egr valve gaskets on either side of the header.

Cheap insurance against a leak, most aftermarket exhaust come with new gaskets.

what system did you buy?... most come as a complete header back system all the way to your axle back and should include all the necessary gaskets and clamps to complete the assembly... I would however suggest buying new gm steel manifold gaskets regardless if your headers come with new gaskets or not unless they are also gm gaskets

I just got done with my header install. Bought new OEM manifold gaskets and all new flange/EGR gaskets. Cheap insurance!

Use new ones. I just swapped mine and used the originals and I think I have a leak.
