In my opinion using oil restrictors is old school, the thought was if running a solid or roller cam the extra oil was not needed up high and the extra oil would help keep the oil on the bottom end, but since then R & D has found the benefits of the oil being spread out across the engine far out weigh the extra oil do low not to mention the extra windage it creates.
Oil helps keep the stock type rockers cool which create tons of friction and it keeps springs cool too which help them retain spring tension with high lift cams.
When using a solid roller the extra oil helps keep the pin on the roller well lubricated and cool which is a major weak point.
Unless your keeping your engine reved up in the 5 to 6k range for long extended periods of time you wont need oil restrictors.
