After reading all the posts to this time, I'd vote carb flooding. Possibly complicated by a plugged crank vent system, either pcv/road draft or oil filler/air filter vent.
While a crack in the exhaust/crossover passage under the intake could cause blowby, it wouldn't cause gas fumes in the crank case.
