Tappet clerances on twins

I've just been reading a 1957 book "Motorcycle Maintenance and Repair" by F W Neill who is billed as the Service Manager of Associated Motor Cycles Ltd.
After going through the adjustment procedure for tappets and the usual .006"/.008 recommendations, he then says, and "I quote:"If speeds over 85 mph are not desired, rocker clearance can be reduced to nil for inlet and .002" for exhaust, with a cold engine."
Really? Any comments from people who know much more than I about these engines.
