Gets hot and stalls out

I am leery of header wrap as I toasted a set of headers on of all things my '88 Dak with a 125 HP V6. I wrapped them to keep the heat out of the engine compartment but in about 3 months, the totally fell apart flaking rust all over the place and naturally massive leaks. Edelbrock said that they could not warranty them as I wrapped them which caused baking of the carbon out of the mild carbon steel. Or so they said.
