Funny you should mention air cooled stuff, because they are the only folks that really seem to worry about head temperatures. Porsche/VW are one group, but a group with more research are the ultralight fliers - probably because they can't just pull over to the side of the road to let things cool off. Their limits on head temperatures vary depending on the engine, but are in the range of 450-550 F.
