Could you get a couple pix of this fabrication? If you can't post them, PM or email me and I can do it.

I took a set of warped MoPar manifolds in to be machined back to flat. Machinist said "Out of a Van, Right? Poor air flow gets'em all the time."

On this topic, I believe we can abuse our manifolds. How? By diving right into the first gas station off the Interstate, and shutting down immediately. Cruise around slowly for a couple minutes. At least let it idle a little, then shut down. Can I prove it? Nope, but we've had less warping/leaks/loose/broken fasteners than many have reported.

. I think you are right. A while back someone on here posted that he observed the manifolds glowing read after a hill climb. He did some testing and concluded that several minutes of idling brought the temperature way down. After replacing manifold gaskets once and cracking the exhaust manifolds a year later I installed headers and that fixed the problem and also reduce heat under the dog house. Adding another layer of insulation eliminated the hot foot.
