A high voumn pump does squat for the cam lobes or lifter wheel,that's a myth started by Re-ignited that everybody has fallen for.The cam lobes are strictly oiled by the oil flung off the crank,there is no pressurized oil fed to the cam lobes.High volume oil pump would be first on my list to try to save the cams (assuming you have a 5.7).
Your theory might be okay if there was any amount of oil forced past the lifter body,but the groove catches most of that oil and guides it to the bottom of the lifter,not the top,so it's not really gonna make it onto the roller,plus with machining tolerances these days,there isn't much oil that travels past the lifter body and the sides of the lifter bore,as the lifter is a pretty tight fit in the lifter bore. As observed by the scoring on the lifter body.I watched the second video and he doesn’t take in to account that when the lifter goes back and forth in the lifter bore, some oil that is on the outside of the lifter body will be pushed towards the roller. The narrow section around the lifter body probably helps to facilitate this.
I take issue with the second video in particular. Yes, there is an oiling issue, but that hasn’t prevented many, many Hemis going over 300k. Every engine has its faults. Toyotas vaunted 4.7 V8 has a weaksauce timing belt, Ford added cylinder deactivation AND put the wet belt back in its 5.0 Coyote.

If you take the oilpan off,you can look up from the bottom and see the cam lobes hung out in the open in the crankcase,with nothing feeding pressurized oil to them
Spend 20 minutes and watch these 2 video's,and you'll start to see why the high volumn pump does nothing to get more oil onto the cam lobes

A Closer Look At The Mopar Gen 3 Hemi And It's Often Fatal Flaw
Our first video concerning Mopar's Gen 3 Hemi's notorious camshaft and lifter failure phenomenon caused a lot of discussion and controversy. It has nothing ...www.youtube.com
And just what do you take issue to,pray tell clue us in. All he's doing is pointing out some of the flaws that moron Hoover designed into the redesigned VVT block.FCA should have left that man retired instead of dragging him out of retirement to redesign the block for VVT.Even Hoover knew there'd be issues with moving the cam farther away from the crank,and blocking alot of the crank splash making it to the cam lobes,and that's why he spec'd a "billet" cam for the VVT engines,but of course the bean counters killed that,as it might add another couple bucks to production costs,so the engines get a poorly hardened cast iron core cam.I take issue with the second video in particular.
