Header gaskets

I finally gave up on the factory gm metal manifold gasket and bought some squish able perforated metal header gaskets for my lg long tubes and no more leaks now I can tune it!

I just bought a set of used LG long tubes. In reading some posts it seems the guy I bought them from had some issues with leaks too. I'm wondering if this is a common thing and if i'm going to have the same problem. If what you done seems to be the solution it would be good to just nip it in the bud but not sure. What made you try this? Can you share any website/product info? Thanks!!

I used the ARH gaskets that came with the headers and they were great. When I put the heads on I used GM gaskets and the leaked. Went back to the ARH thick gaskets and no more leaks. Good luck.
