Offy dual 4-barrell 360 high rise manifold

Ok, so I am building a 455 for my 48 Olds Keith black KB886 pistons. Roller cam and lifters (Erson). So I stumbled upon a Offy dual four barrel mainfold with dual 500 Holleys in perfect condition. Would add a cool factor to the build. I also have a Edelbrock RPM and no carb selected yet. Is the Offy a good choice or should I ignore the cool factor and go with the Single carb on the Edelbrock? Did a site search and could not find any opinions. Cam spec's attached.

Thanks in advance

 

Are you a tuner or a driver. If you don't tune or like to stay with the single carb, if you don't mind tweaking on occaision (not meth related) than go with the 2x4 and be happy.

 

Tuner and driver. Don't mind tweaking always doing something anyway. Just never run dual fours before.

 

A pair of 500's is a bit on the light side for a 455 (my opinion).
