If both bowls empty are they dripping out or is it being pushed out by more fuel? If the fuel pressure is too high it'll force the fuel out of the carb and into the engine until the pressure bleeds down enough for it to stop. This is usually a vent problem. If not then I would take the carb off, fill the bowls then place it on a ladder where its high enough I could get a look at where the fuel was coming from and go from there. Can't say I ever heard of it leaking from both front and rear bowls as usually its just one bowl.

Is this a modified Holley carb? Sounds like you have the wrong gaskets installed, maybe a blown power valve.

You mention "after a run", any chance the carb base is getting so hot it's boiling/purging the fuel out?
