What are the best headers for 66 Dart V8?

:-DIv'e heard spitfires have gotten alot better since the earlier versions. for $350 US. you get headers that fit with no cutting and delivery time is better as well I hear. I also hear Laysons bought the pattern. Performance wise....who knows, who cares...they flow better then early A manifolds. I am considering them. Times are tight...1200 headers? my wife would castrate me
Yes I know. I was single when I was building my car back then and I could do whatever I wanted. I was doing a lot of travel work and was making extra money so it paid for my dart build. At the time that's what the custom made mandrel bend headers where going for. Jysnflem
