I use FEL-PRO exclusively, and I coat them with a "Copper Coat" gasket sealer. This seems to give me the best service in longevity. I have some header gaskets that have been installed for several years. Every one of my (four) vehicles has headers on them. I also put the header bolts in with "Teflon Tape" wrapped around them. This practice came from an article in a engine build book. The bolts stay where you set them and they do NOT back out or come loose during normal use. Taking the bolts out later is real easy, too.
