About the Holley, if it is a double pumper then it has mechanical secondaries right? They make for rougher street driving and if it is flooding then it could probably use a rebuild or your engine could use a milder carb. I presume you mean the carb is a race carb and you suspect it doesn't match the engine. I would agree with you on that. If the rest of the engine appears stock or you know that it is stock, you would be better off with a different carb, rochesters are good and have very good manners for a street machine.
