440 exhaust flange gaskets

Does anyone know of a better than stock manifold to exhaust pipe gasket
for a 1968 440 HP
I have had my manifolds resurfaced and when I install the gaskets they last for a short time and start leaking again I wonder if there is an after market 2 bolt gasket that might last longer
Thanks

Rickyr, make sure both surfaces are flat and clean, and the way to go would be copper.But,I don't think anyone makes them,so buy some copper and make your own.
Try:http://basiccopper.com/samplerpacks.html

good luck,john

Are you still using a H pipe ? If not your pipes may be swaying and causing your problem.
