Dougs # D454 Early A body headers 65 Valiant (Need opinions)

BIG question.........are you installing an Alterkation "K" member??

Per Summits listing, the D454's are for early 'A' with Alterkation "K" member; the D450's headers are the D-Dart headers.....BIG difference between the 2!

Don't know a thing about the D454's; have a set of the D-Dart 450's, I like them.
