chevy 350 engine smoking

i have a 1973 chevy 350 engine that smokes a blueish/gray smoke at idle sometimes. it smells like gas but i have replace the carb. and adjusted it out. the engine runs and starts perfect hot or cold with plenty power and no rattles.the engine been rebuilt about 4 years ago and have been setting up every since. should i just drive it a little bit and see what happen because i only have driven it about 20 miles since i had it. from the best i can tell it only smokes at idle because going down the highway i didn't notice any smoke. i have had a vehicle that had bad valve guides that smoked very bad at start up but this smoke is not hanging around like that it comes out in little puffs and some times none at all.. please help
