Taco Warmers or Performance Headers?

Those are indeed PowerPipe DC (DC for dual connection). By definition they are not headers. I define them as a divided oversized exhaust manifold. The runners into the manifold chamber, the manifold chamber, and the exhaust outlet are significantly larger than stock. There was vehement debate over on SlantSix.Org concerning their benefit.

I have a PowerPipe SC (single connection) on my 73 Dart. It is essentially an oversize exhaust manifold without a heat provision for the carburetor. What I can say for the SC is that the exhaust outlet fits a 2¼" pipe perfectly, something the stock manifold will not do. Because it has no heat riser, it is like a header.

RE: Taco warmer. I haven't tried cooking on a /6. It would not be difficult, however. For things you can do in this regard, search Amazon for a copy of Manifold Destiny . I tried some of the receipes with a V-6 Dakota. Not bad.

Not recommended if you are leaking fuel or are using a road dump tube. Putting fatty meats, even in foil, on top of exhaust manifolds is not a good idea as an underhood fire could result.
