Hi volume oil pump vs standard volume pump

Hydraulic flat tappet, converted to solids because of bleed-downs.
But I have a set of solids on order to replace them because I believe the oilband is too high compared to the camfered lifter-bores in my engine.
(Provided the lifterbores themselves are still into spec).
Let me guess they were Comp Cam lifters that bleed off?
I was told by some Cam people not to run solids on a hydraulic grind. Did it work for you performance wise?
Good luck with your bores I know there is a manufacture the moves the oil band down to get away from the chamfer.
