what make model of carb for '64 slant 225

I had continual problems with a Holley 1920 on my 1969 Dart, over 20 years. Always idled rough and wanted to die when you left a stop-light, sometimes stalling. Mechanics said "bad valves", intake leak, ... which I paid for several times, plus at least 3 rebuilt carbs from auto parts. After a complete long block engine ran rough, I tried my 4th carb and it ran smooth as silk. Many bad rebuilds out there. I don't like their sealed metering block which can't be rebuilt.
