Restricting the lifter galley oil is a practice carried over from the "old" days.
It is not done at my shop any more. 30 years ago, yes! What the previous post (Reed) pointed out is a good explanation. The things that made restricting necessary in the old days have been vastly improved by modern technology. Now, other places in the engine need the oil more than the bottom end did in the "Old days". That last statement means the valve gear needs the oil to live longer.

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.
