I hope we are doing the oil mods to take advantage of a higher volume. lol
small holes can't make use of more volume.
more pressure but not volume

My son said if a motor is fresh and built right with solids a standard pump is good enough. But he takes every pump apart and checks clearances.

I think Some of these new chinese Hyd. lifters you need a HV pump.
