I did a valve cover gasket replacement and three of the retainers circled in red were missing, replaced by washers. What are these things called, so I can narrow my search down and get the correct part?
What are these called?

I'm not sure what they are called, but I might have some if you need them.
I think you circled a torque limiter sleeve.

OP
Looks like these are no longer available new, but now I know what they are called. Thanks!
I just did my valve cover last night and have them if you need them. Didn't use them with the new valve cover.
Somebody on etsy of all places sells them, GreenHornGarage or something like that. No idea if they'd catch on fire?
OP
I looked at those already. Like you said, I have no idea if they will melt or burst into flames!
Hmmm....A torque limiting sleeve that will collapse easily (due to 3d printed plastic). Pretty sure that's not going to work as intended.
OP
It will work well on one side of the purchase, i.e. making money for the seller!
I'd check with Davey's Jeep. They seem to have a ton of that hard to find stuff. They hooked me up on a ton of stuff for my auto swap.It will work well on one side of the purchase, i.e. making money for the seller!
Heat is all I'd worry about, I have 3D printed bushings on my seats and they take about a million times more stress than the few foot pounds of force those valve cover things take.
That may be...but the only way those bushings can work is by provided a hard, non-compressible surface for the bolt to generate a load against. If the plastic continues to yield before you hit your target torque, the gap is going to continue to close. In this instance the limiting device is probably there to prevent squeezing the gasket out the side of the valve cover or bending the valve cover, both of which issues will generate leaks.
Its the same concept as the body mounts. There is a steel sleeve in the mount, so when the body bolt is properly torqued, the steel sleeve nets out on the steel upper portion of the mount which creates a solid connection and generates some stretch in the bolt. This prevents the rubber mounts from squeezing out and not properly supporting the body.
OP
The rubber seals/grommets are included, but not the metal torque limiter sleeve.
