Personally, I feel, if the head and manifold surfaces are flat and not pitted, you don't need exhaust gaskets...
The manifolds have such a large sealing area and are so rigid that gaskets shouldn't be necessary, especially if you're running a free flowing exhaust system.
I've had more trouble with gaskets than I've had running either naked or with Hi-temp RTV for a seal...
