I really like the sound of a BBC when you can hear the headers tubes ringing at idle. Exhaust sound, especially muffler choice is very subjective. But if you like a nice aggressive exhaust, headers are right.
I'm a big fan of the day II look. A good aluminum intake, Holley carb, old set of white colored headers is a pretty timeless look. It's your car so do what turns you on, but you've got my vote for a set of headers
