Not sure how they came to that conclusion?  The 
heads should have enough openings to allow the 
crankcase to vent through a valve cover.  Not 
ideal, probably lead to sludge, but should be 
enough to prevent positive crankcase 
pressure.  The down draft tubes were cut on the 
bias to encourage a suction effect as the vehicle 
moved down the road which gave more efficient venting.
