I've been running a HV pump for the last 50k miles without issue (knock on wood) so there's no reason not to run one, especially since the 4.0L engine (and the stroker on which it's based) doesn't have particularly tight bearing clearances even when new.
Just keep in mind that the body of a HV pump is bigger so you'll need to "massage" a small section of the oil pan with a ballpeen hammer to gain some clearance.
