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..

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  :alan2cents:   :cheers:
