You could tread teflon thread sealer , it won't harden but might add enough resistance

If your not hung up on stock looking hardware.....  These have a nylon button inserted into the tip area, they don't loosen due to vibration.. You have to actually put a wrench on them...

I choose 7/8" length which is probably about right, but McMaster Carr has lots of options..

How about Loctite ?

Honestly loctite doesn't work very well in that application.. The heat causes it to release... Plus it's hard to get all the oil residue completely gone before application....

I have been using Vibra-Tite for other applications https://www.vibra-tite.com/threadlockers/medium-strength-removable-threadlockers/hot-lock-extreme-high-temperature-threadlocker/.

OR, if you're not obsessed about it being "stock" , you could install one of the valve cover stud kits and be done. Just my
