Ahh, just looked at your pics. The a/c lines DID have to come off...that sucks. I’ll check your pic above for the torque specs
AC lines stayed in place. Radiator hoses, fan, and shroud came out to make working space.
Torque spec for the cam carrier to cylinder head bolts is 22 ft-lbs, tightened from the center out along the center row, and then alternating from the center between the upper and lower rows.
RTV sealant officially goes on as one 4 mm bead all the way around the outside of the cylinder head mating surface and up on the side of the timing chain cover, looping around the bolt holes. No voodoo at all. Prep surfaces as one normally would. On the cam shaft cover, a dollop of RTV where the timing chain cover and cam shaft carrier meet. I had trouble with the rubber gaskets staying put during installation, so the corners got a drop of RTV here and there to hold it in place.

You need two smaller and one bigger O-ring per side too, I used generic EPDM ones, but of course Toyota will happily sell you the same for $6 a piece.
If you're DIY'ing it, you do need to mentally prepare yourself to pull the timing chain cover, and either have parts on hand for it, or do this when the parts stores stocking those parts are open. If you drop something in behind it, accidentally release the tensioner with no chain to hold it, or drop the chains, it's what you'll be doing.
By the video it looked like the chain tensioners are captured, unlike VW which pop out, but I'd never assume they are. And when you mount the intake cam phaser, it's easier to seat the timing chain on the tensioner guide beforehand. Once each side is done, give the engine two rotations to make sure some valve isn't going to hit a piston.
Having done it once, I'd do these for 11 hours book time ($2200) plus parts all day long. And most certainly over any money having to work on a VW VR6 in a Eurovan. And the burning oil smell is finally starting to fade. Hallelujah.
