Barry- The Motronic ECU determines when they open and the schedule is different for various models. On the F355, the schedule is different depending on which gear you are in. Stef has published the F430 schedule shown below, and I know when it opens on the 575M. The 550 says to check the valves at 5000 rpm and wide open throttle to make sure they are opening.
The valves open on the later cars at a combination of throttle opening and rpm (earlier were rpm and WOT), so you may be able to sneak by with low throttle setting and 4000 rpm. Let me do some looking in the WSM, but I do not remember seeing specifics.
Here are Stef's F430 schedules. Trouble is the F430 uses Motronic 7.3, IIRC, and the 360 is 7.1.1. Also bypass opening on the F430 is also affected by the mannetino setting, but do not think being in normal or sport affects it in the 360. For the test, though, I would be in normal just in case.
You should be able to reach 4000 rpm easily on about 1/3 throttle.

Every day I look around, and if nobody is shooting at me, it is a pretty good day.
