I just did this on my 68 Imperial Convertible. My understanding is you can warp the manifold. Check for loose nuts first. Then check the bolts and gasket at the connection between the exhaust pipe and the manifold. Replacing the manifold gaskets is fairly simple (8 bucks for the actual gaskets at Kragen) and a couple of hours of labor. It took me about 3 hours, but then again I'm not very bright. When I replaced mine, it turned out that my manifold surfaces were in fact warped as well. To have the mechanic machine them down and get me on the road was less than 200. Be careful with the bolts that the manifold(s) slips onto. If one breaks, you will be hurting in the worst way. Now it sounds absolutely awesome (the little I actually hear) and was well worth the effort. Have fun.
