We've been moderating cam oil feed since the mid 80s. When Porsche came out with theirs in the 965 (91-92 Turbo) we investigated their version. I believe the 965 cam feed fittings are a little too restrictive.
We still make our own fitting with a slightly larger oil passage and when we encounter the Porsche version we bore them out (slightly).
The modification is a good one if you consider what your goals are.
