They should work. You'll also have to replace the fuel supply line from the fuel pump to the carburetor. Depending upon what car your 455 came from, I would chose the carburetor for that car. Even though the different carbs look the same on the outside, it's possible the fuel metering rods and jets might be different for the varied applications. Just a personal opinion.
