Drag Headers

SO I need new headers for the little ol 360 in our valiant,Doesn't look like I have many choices other than the TTi 1-7/8 chassis headers SO-Full track car-No street-whats your opinion on paying the extra $200 for the coated headers or do I just get the plain steel and paint the outside with a quality heat paint??????????? Does it really make a difference on a full out drag car??? Thanks guys I value ALL opinions--My engine builder says go with the coated but again its not his money--Thanks steve
