Jeff, any NAPA, or at least the one I use can anyway, ought to be able to get a high temp gasket material that you can use. Most manifolds won't get over 500 degrees, so as long as you have a temp rating of that or above you should be good. If I remember the last batch we bought, it was relatively pricy too. We've used it several times for manifolds on small engines where it just wasn't a critical thing, and where "factory " gaskets weren't available. But, and there's always a but, if your planning on using it on a multi-cylinder engine, and on the manifold to head joint, as a mechanic, I'd really have to suggest biting the bullet and going with the factory gaskets. Their expensive, but they arer designed specifically for that application, to withstand both the heat and the expansion/contraction of the manifold while retaining a seal. Alot of times with the material like I'm talking about the manifold may not pull up evenly and seal, allowing exhaust to blow by. Eventually soot will build up in this area and when it rains, etc. will trap moisture causing severe pitting of the area. If that happens then your gonna play heck ever getting anything to seal.
But that's just my opinion, based on experience....hope it helps....
