i've found that it more in the type of fasteners than the gasket that lessens the chance of leakage, and flange thickness and support also help

Not sure you can get them for your headers. I use copper gaskets on my Hemi stuff. I have used the copper gasket maker by Permatex. Tip make sure it isd good a dry before firing or it will cover the side of the trailer and PIA to get off.
