Question What Is The Thickest Header Gasket ???

I've got a header leak on my passenger side. I think its slightly warped on the far back side. I'm looking for a quick fix for right now. So my question is whats the thickest header gasket i can buy to stop this leak? Oh and the headers are pacesetter mid-tubes.
Thanks

+1 - Percys is the thickest and IMO the best out there.

I only have experience with the Percy's Seal For Good/Dead Soft aluminum gaskets, and whatever Kooks provides with their headers. The triple layer Percy's were much thicker than whatever was supplied by Kooks.

I like both the Mr. Gasket copper gaskets and the percy's gaskets. Although on my latest build I kept having a header leak and finally doubled up on gaskets and used both the copper and percy's gaskets, lol.

I've always had good luck with the Copper ones that I have got with my Pace Setter Headers.

For Percy's don't do it as they are pretty darn thick already. They are multilayered and designed to crush as you torque them down as they are aluminum. Other brands you can double up but not with Percy's.
