Looking for recommendations for what all parts wise would be needed to bullet proof a 5th gen

1) Bullet proof the motor? Drive line? Everything?
2) Budget?
3) We have some ideas with the manifolds, but as new as those trucks are no one knows what "the" issue will be with them in 10 years. Especially with e-torque that I assume you have, that may be a great system or it could be a grenade with the pin about to fall out. Or the Hurricane which is a total unknown, so good luck. We won't really know for at least a few more years.

High volume oil pump would be first on my list to try to save the cams (assuming you have a 5.7).
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.
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

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.

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 get your theory,but you're thinking the lifter is acting like a pump,when i don't think it is as the groove doesn't get enough oil to actually act like a pump

Bulletproof: Kevlar hood, grille, fenders, Kevlar shield under entire engine? Lol

Me thinks it helps if U got a Tuesday/Wed/Thursday built truck and not a Monday or Friday ride and also pre-covid (sic)

The OP has the truck in his profile as a '22 6.7 now, as for bulletproofing I'm wondering if he thinks the Cummins is like the Powerstroke/Duramax that have known weak points with the engine.
Maybe upgrade the grid heater and if want to go to extremes give the exhaust system a weight loss treatment.

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. I’ll take the Hemi any day, any time

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.
Hoover basically designed a valvetrain that was good for 8500 rpm,but crappy as hell for a daily driver that see's alot of idling,and is expected to last well past 150,000 miles before it needs a major repair.
Anybody with an eye an ^$$hole could tell sticking a big ole oil passage under the cam that blocks alot of the oil flung off the crank onto the cam,and moving the cam farther away from the crank isn't a wise move.Why didn't they lay the block out so the VVT oil passge was above the cam,that would of accomplished a couple things,it would let more oil off the crank make it to the cam,and would have also kept the crank closer to the cam,while also keeping the lifters on a better angle to promote oil flow past them.The way it's designed now,it's basically designed to fail ,as common sense can see they didn't do the consumer any favours,they did it,to keep people buying a new vehicle.With the technology available today,the amount of cam failures in the VVT hemi's is totally unacceptable

If you hate it, why do you keep it around?
