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
