Holley 6210 DP Rebuild/Modification Questions

I just won this Holley list 6210-3 1545 on Ebay.
I used the same carb on my 318 in my 71 Dart 10yrs ago and am going to use this one on my 318 that's going in my Valiant.

Can I make this a center hung float/ dual feed carb by putting the proper bowls, floats, feed line on it?
Also, would I have to change the metering blocks with this mod?

Going to buy a Quick Fuel Kit #3-206 rebuild kit for now.

All suggestions and help are appreciated!!
