Is elec. choke needed on dual quads

I am converting my 470 stroker to dual quads. Should I use an elec. choke on the front carb. I noticed on all the Indy motor pics of duals they do not use one. I do not have one on my single carb set up and it starts up fine. I origionaly was going to EFI and my cam has a LSA of 13 degrees but my pocket won't let me. The duals are for coolness more so than power. Comp. is 11:1. Will the duals over carb it using Edelbrock 500's, it runs rich now just using a holley 750?
