TTI Shorty Headers VS Doug's Long tube headers??

I have a 408 Stroker with the aluminum heads on order from Blueprint for my 69 340 Dart and they stressed that I really need headers. I have never owned a car with headers before. Cost aside, what are you opinions on the Doug's (https://www.summitracing.com/parts/dou-d453) and the TTI Shorty's (https://www.ttiexhaust.com/TTi34025.htm). My main concerns are ease of installation and clearances. The car is also a 4speed. Whatever I buy will be polished & ceramic coated. Looking for your experiences as anything from stock is new to me. Thanks
