Although not a 911, the Apfelbeck (sp?) Project has been developing aircooled three-valve heads for the Porsche 914 and I'm pretty sure there are running prototypes. They worked out the cooling problems with getting air around the valves and behind the combustion chamber for cooling. Pretty neat stuff.
