Which carb is "right" for 1971 383 ebody?

I keep seeing people advertise 2 different carbs for 1971 Ebodys with 383. Some say carter and others say holley. Can someone shed some light?

1971 383 4bbl carburetors:

auto
Chrysler part #3512 842 w/ N96 HOLLEY model-4160 R4735A B&E-bodies orange engine
---------- B'CAST: ENG-419 & CARB-42
Chrysler part #3512 830 w/o N96 HOLLEY model-4160 R4668A B&E-bodies orange engine

Chrysler part #3512 844 CARTER AVS 6125S C-bodies blue engine


4-speed
Chrysler part #3512 849 w/ N96 HOLLEY model-4160 R4734A B&E-bodies orange engine
Chrysler part #3512 848 w/o N96 HOLLEY model-4160 R4667A B&E-bodies orange engine

Thanks. That clears it up. I never found that info which separated the carbs by car. Makes sense.
