Another Cam and Jetting question for IDAs

I am currently running a 347 with a Demon 750 and want to switch to 4 x 48 IDAs. I have the carbs and the chokes I have are 37s but after reading here I will bump them to at least 40s.

I am running cnc ported aluminum Avenger 215 heads.
Intake valves are 2.05
Exhaust valves are 1.6

Hydraulic Cam:
Intake lift 576 w/1.6 Rockers
Intake Duration at 050 is 234
Exhaust lift 592 w/1.6 Rockers
Exhaust Duration at 050 is 242
Advertised lobe separation is 112 but actual was blue printed at 111

So... Will it run ok with IDAs? Any thoughts on starting jetting? All these carbs came from VWs so I need some place to start for jetting. I know everyone will be different, but just need a base line. Thanks!
