Best explanation I've seen so far for Hemi cam/lifter failures

So the Reignited Cycle and Auto guy on YT did a test on a high-mileage 5.7L where he installed a HV Hellcat oil pump and it bumped the hot idle oil pressure up from something like 10-15 psi to 25+. He reasons that should help with lifter failure due to extended idling.

I still haven't gotten around to doing anything with my 2014 5.7L with failed cam & lifter but when I do get lifters they'll most likely be aftermarket units like Hylift-Johnson. But then I intend to build that engine with a hot cam, valve springs, single-plane high-rise intake, long tube headers etc.

I imagine with a Hellcat oil pump and good replacement MDS lifters and cam it should go another 100k miles. But it has been a while since I looked into this stuff deeply and there's always new info and "fixes" coming to light.
