Quad carb setup information help

I tried to work those 600 cfm 1850s on my 440. Mounted straight. I was told about changing bleeds which unfortunately those carbs will require disassembling drilling and tapping . The metering blocks will need to be changed and then set up properly. I gave up and bought 2 450 Quick Fuel carbs. Dedicated dual quad carbs. Needed to jet up and change the power valves because I have like 15 inches at idle and 21 at cruise. Now I don't have extra money a d this was a bitter pill to swallow after I had spent so much time and money on 2 1850s. Fat at idle. Couldn't make them work. Tried tried tried. Street car.....makes a big difference. Race? Street? I can tell you what worked for me.
