I'm with Adger ( Whoda thunk?) I have not used restrictors for years. I used to tap the oil passages (5/16" USS If I remember correctly) and screw in drilled Carter carb jets as restrictors. Bottom end oiling in a sbc is no problem at all. With 1.8+-1 intake rockers .800"+ intake lift and 1000+ lbs spring pressure over the nose, pushrods need oil. Myself and many others went through a period of burning ends on pushrods a couple of years ago. More oil up the pushrods cured mine. I still modify my intake pushrods for that.
