It is common for the ends to leak if you use the cork gasket ,a bead of silicone is best there and do not use the cork . If it is pooling beside the carborator it could be leaking from a valve cover gasket ,do you have a PVC valve ,if not it will build up pressure in the crank case and blow out gaskets and front and rear seals .

Like RPM suggested, make sure you have a good PCV path.   The PCV hose connection on a basic Holley is under the rear float bowl.
