I am in the process of picking a replacement header for my 67 Chevelle. Car is a 396 and I currently have 2" primary x 3.5" collector Hooker Comeptetions. I want to drop back to 1.75" primaries and a 3" collector to build more bottom end torque.. I am down to 2 choices. Flowtechs or Hedman's. Called Jet Hot and they recommend the Flowtech as they seem to think they are a better fit than the Hedmans. Anyone have any real world experiences with these two headers?
