Are the oil feed holes on the side of the lifter and not in the oil band if so they are all ready restricted no need to use restrictors.

I dont know where the oil feed hole is, yet, as the lifters are being made...itll be 3 weeks, or so, before they get here... Thanks!

Brent, It's not so much the oil hole location as the oil groove relief in the lifter. On a Pontiac block the relief is very close to the. bottom of the lifter bore, allowing oil to escape. I believe some bearing problems I had were related to this condition. So, I would use the restrictors I think he machines the lifters to work in Chev & Pontiac both. I have the Schubecks in both cars, 180# @ the seat, 6200 through traps, no problem yet! Good luck! Bob Michael.
