Yeah, It Shows That The Flipped Gasket was the Issue...

I'm tending to agree! @Max1196 nailed it in post #3. I also wouldn't recommend assembly without gaskets. A lot of Chryslers didn't use exhaust gaskets from the factory, but they were assembled with brand new parts with no pitting from rust or warping from heat. I would use the manifold gaskets. That said, I prefer the one piece kind, if you can find them.
