Trying out a spreadbore carb on the Duster.

So the LD340 intake on my Duster was at some point milled out (quite well I might add) to a spread bore design. I've been running a Holley Double pumper for the last few years but have always wanted to try a spread bore carb to get rid of the adapter/spacer. I recently got a Carter AFB 9635S off evilBay. it's set up with: 100 Primary Jets, .70 x .47 Metering Rods, .095 Secondary Jets, and 5" Step-up Springs. Is it a decent carb? Will I be disappointed with it compared to the Holley?
