This Thread is just what I needed to know. I see that the Mopar intake manifold comes with two rectangular, stainless plates that should be placed on the head side of the gasket with high temp silicone to block the heat. I wonder if they need to be formed to fit inside the port on the head or just laid flat on the port. I'd think that just laying them flat might deform the gasket and create a gap that would leak exhaust.
