440 header choice

I've been thinking about possibly putting a 440 in my '69 dart. The hardest part, from what I've read, seems to be getting the headers to fit. Would Schumacher headers or TTI headers fit better? Are there any other brands? I dont think I want fenderwells because I want a sleeper look. What are herb McCanndels headers? How did they fit the 440 in a dart from the factory? All inputs and opinions are welcomed.
