If too loose or too tight, they can work themselves undone. When that happens in a bigger way - if the cam was ground correctly in the first place and is not worn out - they'll actually cause the adjuster to tighten up, loosing all clearance and if left to go further, won't allow the valve to close.

I wonder if the threads in the rockers and the adjuster screw themselves may be worn?
You shouldn't have an issue with the rocker gasket - you can use the same ones many times if you don't overtighten it.

Or get a silicon one which is definitely reusable

I change the adjuster screws and nuts when the thread is worn out. which it is sometimes.

I have been driving a-series engined cars for quite some years and adjusting valves while easy enough often results in that one valve needs adjusting two-three days later as the nut on the adjuster screw has worked it self loose. I change the small adjuster nuts when needed and always tighten them very tight, but even so they work their way loose. this is quite annoying when I have just put in a new rocker cover gasket. what do you do to avoid this?
I've never had this on any engine ever, I've never seen it either.
Either the nuts aren't tight enough, are too tight and the threads are damaged or there is something wrong with the threads in the rockers. I would suggest another set of rockets and see whether it keeps happening.
