Carbking,take a ride over to my place,you can see two of my trucks have Holley 1904's that don't leak,and have never leaked.No glass float bowl,so nothing to watch
Since Holley 1904's where used by the millions on Fords,IHC's and even some GMC's,I think one should blame any fuel leaks on the mechanic and not the carb.
One thing to keep in mind,any multiple carb setup where all the carbs open at the same time,it would be nice to have matching airbleed and power valve restrictions.Even the dreaded Rochester b was made with many different specs.
