Exhaust heat shield, paint?

Autoxcuda, you are correct. When I answered this question, I was thinking he was asking about the heat stove that was put on after the engines were painted. after I saw your response, I when back and read the question again and realized I have not read it right...

On 70-71 HP 383 and 440 cars there was a black heat stove that bolted to the exhaust manifold after paint.

And mid 70's small blocks had a bolt on heat stove like that too. There are mid 70's HI-PO drivers side exhaust manifold that are nearly like 68-71 340 manifold inside but have a cast in flanges for a heat stove to bolt too.
