Still haven't found a YouTube video on this.

I'm gonna go out on a limb here,and say if you need a video to torque the intake bolts,you probably shouldn't be working on your truck.Just my 02 though. Red posted the torque sequence,and i gave you the size of socket you needed,plus gave you a good tip of where the bolts are ,it's up to you to go look at the manifold from there.Still haven't found a YouTube video on this.
Very little I can do anymore. Don’t have the skills or correct diagnostic tools. That being said, I can torque bolts if needed. Lol again thanks for the advice and diagram for proper sequence.I'm gonna go out on a limb here,and say if you need a video to torque the intake bolts,you probably shouldn't be working on your truck.Just my 02 though.

Sorry to be the heterodox again, but while the theory is good I'm not so sure the expansion/contraction of the intake manifold is causing the intake bolts to turn (loosen).
The gasket used in this application is a elastic rubber-like compound O-ring. Over time they lose some of their elasticity due to heat. This results in loss of elastic pressure with resulting loss of force against any two components being sealed. Like a lot of intake manifolds these days, new ones almost always come with new O-ring seals.
I've asked techs if they've ever found an intake seal that cause a problem on a Hemi, and the answer has always been "no". Of course, it doesn't mean it can't happen. But I suspect periodic retightening is only bringing the intake surface closer to the cylinder head and eventually the intake surface will be in full contact with the head. This could cause the intake to crack.

2019 Ram 1500 Billet Silver Quad Cab 2WD, 5.7 Hemi, 8HP75, 3.21 axle, 33-gallon fuel tank, factory dual exhaust, 18” wheels. Build date: 3 June 2018. Now at 82990 miles
Checked mine today, I don’t have a small torque wrench but followed your advice with the 1/4” drive. Most were tight but did get a couple that turned 3/4 to 1 turn to feel as tight as the rest. I decided to leave the engine cover off. Thanks for the tip Wildone!This hasn't been talked about for awhile,but check your intake manifold bolts.They call for 108 in-lbs or roughly 9 ft-lbs of torque,and they should be checked at least yearly,as they do loosen up. I've been doing mine at least twice a year on all 3 of of my hemi equipped vehicles.They should be checked and torqued when the engine is cold.I just use my calibrated hand and a 1/4" drive rachet / 6" extension and 5/16's socket and just give them a twist by hand,but if you don't trust your hand,an inch lb torque wrench should be used.There's 10 of them on 5.7's and 6.4's. I've done them enough,i know the torque sequence ,but if you don't know the sequence it's easy enough to look up
