The "Opening Up" of the slot is a fairly common thing to see but with that and wear on the frame lug you get too much "slop" I have before now carefully straightened the stand for and put a shim washer under the bolt head to keep it tighter.
Its been a few years since i did one but memory tells me the thread tightens up to a shoulder on the bolt so the bolt does not "squeeze" the fork tight. This means a shim between bolt head and outside of stand will stop it opening up again.Propane should be hot enough.
I think it should do, it's just trying to stop the force all concentrating on that sharp internal corner where it naturally wants to go.
Just to give you guys an idea of where my head is with this project right now... I was about to ask a cam chain question that was already discussed awhile back on this very thread. I just noticed that I've twice - on this very same page, even - brought to your attention my thought that the bike might have fallen or been in an accident. Sorry...
If that lever is cheap I would buy it, otherwise fix the old one. A bit of heat and a vice should straighten it, fit a new rubber and it's done. 🔧👍
