Dont use them if you are building street motor,rollercams, especially mechnicals, need sufficient lubrication when driving low engine speeds(idle,etc).Hydraulic rollecams wont work at all with restrictors!!!
Restrictors are mainly used in race-engines witch sees lots of high rpms,so there will not be so much oil in cylinderheads or liftervaley,more in oilpan.
hope this helped,joni
