I have had fewer engine related oiling problems since i starting using restrictors. Use of a good oil and frequent changes is important as well.

I don't think you should run them, for the little bit of power you're going to save in my opinion it doesnt give the top end enough oil, why run restictors, then oil lines in the valve covers, the springs need all the oil they can get to give them good life.

I always run restrictors. The idea is not to save power, but to keep the oil down in the pan and make sure that the mains have plenty of oil at a good pressure. Without restrictors the valve covers have a lot of oil in them, especially as you get near the end of the straights.

Ney, especially on wet sump motors wth big lift cams/high ratio rockers. I have found the valve springs last alot longer without them. Also the quality and perfomance of oil pans have improved to where you really don't need them. Alot of performance engine builders don't recommend them any more. I haven't used them in over 5 years and have not seen any increase wear in the main or rod bearings.
