...also, as I mentioned, I ceramic coated my exhaust manifolds in black. Black is the most emissive color (think black body radiation), it emits more heat than other colors. While this might be good for efficient heat dissipation from the cast iron manifolds, it is radiating that extra heat to the heat shield and carbs. Maybe this isn't much different than raw cast iron, which is grey, but they sure seem to radiate more heat after I coated them black. Just something to consider. Anyone else have black exhaust manifolds or headers and previously had chrome, silver or white and noticed a big difference in the heat in the engine bay?
