I've use stock exhaust manifold gaskets with headers and they last a long time. Also put some Permatex high temp RTV around them also. Allow time for it to dry like overnight. I've got a Quicktime exhaust electric cutout on my truck and they say to use RTV rather than a gasket so that is what I used and it does not leak. So I would try using both on the header.
