I think part of the problem that is emerging in this conversation hoovers around the concept of "restricting " rather than "controlling". I believe that during the ongoing process of engine development, Porsche engineers deemed the flow of oil the the head/ cam towers was inappropriate/ excessive and that there was no appreciable temperature reduction in excessive oil flow. Their testing showed that too much oil was counter productive. Let's not fall into the oh so American thinking that "more is better". The correct amount (of whatever) is better and determining that "amount" has been our goal (as well as Porsche factory) when developing these old engines.
