I have used a combination of copper and regular gaskets(Mr. Gasket) together to build out a blow out proof set up. It's also a good idea to use a set of locking header bolts.

As long as your header flanges are in decent shape, you do not need thick header gaskets. Use Victor-Reinz "Nitroseal" header gaskets, which are available at NAPA, CarQuest and others. These gaskets have graphite facing bonded onto a perforated steel core. The header flange and head surface must be absolutely clean and dry. Do not use any goop or sealers. Tighten the header bolts from center to outside in several steps, just as you would torque head gaskets. Start the engine, let it warm up good and re-tighten the bolts (don't burn your hands!), shut down, let the engine cool completely and retighten bolts again. Check all the bolts and tighten as necessary for the first week or so, then you will have no more header gasket worries.

You can stack the thin ones to get the thickness if you need more clearance. Soak them in water overnight and install wet then start the engine and retorque like engineguy mentions.

Or you can just buy the good Victor steel faced gasket as he recommends and forget all this nonsense.
