I use copper rtv religiously. Not to much, a nice thin bead (1/4inch or so) works perfect. Let it dry for about 5 min before install. Just not to much that it will squeeze out and then be sent into the turbo. There is also a company that makes copper gaskets and I would think they would be superior to any other gasket.
Use some sand paper and clean the flange of any corrosion, I use a die grinder with a roloc "red" disk attached.
