Never heard of a BMW race cam other than the 336.
Helmut Daehne raced the 336 and then (early 70ies) he was working in the test department.
He probably had access to all parts available at BMW.
I can ask him if that's of interest.
BTW: I asked him about the 336 and he still is very fond of it. Used it even in his enduro "without disadvantages".
