RTV on Header Gaskets ?

Do I apply RTV sealant (spray or tube form?) to the header gaskets, head and header when putting on the new headers? Or do i leave this off since i have copper gaskets ?

If your header flange is flat, you shouldn't need any RTV sealant. IMO RTV sealant is like a bandaid anyway, if you need it, it's not going to last forever and will eventually blow out.
