Does Ferrari use roller cam followers?

There was a question on the Vintage board about oil for Ferrari engines with non-roller cam followers.
Do the current generation of cars use roller cam followers?
If so, when did Ferrari start using them?

My Garage
The older 2-cam Colombo engines had roller rocker arms. I don't think rollers have been used by Ferrari since the mid-sixties.

Is there any concern over possible early cam wear caused by the legislated lower ZDDP levels in oils for use in gas-engined cars in the US now?

several additives available for replacing the zinc/phosphorous missing in modern oils. I use the Brad-Penn oils in older vehicles and if no additives were available, I would use one quart in later models along with the regular grade synthetic.

I too have been well pleased with Brad Penn in my BB512i. I'm old enough to remember using the original Kendall GT Racing oil when it contained 100% Pennsylvania crude...the green stuff. I used it in my Vette, Cutlass and various 4 stroke motorcycles in the 70s.
