have you done something like that with an 8v head?
I have not, but it should be doable. You'd probably have to tap into the oil galley at the rear of the head, through one of the steel plugs.
The only point of reference I have is the old 8v rally engine. Same rpm range, and the last two cam journals did not look the best after ~1500-2000 race miles. The 16v head looked much better on tear down this last time.
