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

Question: are you changing out your "K" member for an Alterkation?? If YES, then D454's; if NO then D450 D-Dart. It's not like there are lots of choices.

Another question: is the car an original V8 car, or was it originally a /6 car with a transplant? If original V8, OK; if was /6 with transplant, are mounts factory, or Schumacher? If factory, OK; if Schumacher then MAYBE (not 100% sure) have additional clearance problems (never used Schumacher mounts).

Others may know more.
