Melted Holley Site Plugs

My Holleys have been fine for 15 years, though I can't unscrew them now.
I have never put ethanol gas in my car.

Just a quick update. 
I sent an email to Moroso tech department to inform them of what happened to me when I used their plugs, part no. 65226.  They emailed me back and said "When and where did you purchase these from? We have kept up with different types of fuels over the years and continued to test these. We haven't had any issue to date but I would like to stay on top of this. If you can provide me an invoice/receipt, I should be able to get you out another set."
The invoice I forwarded to them was from JEGS.
A replacement package from Moroso showed up in my mail box today, looks like the same plugs, but this time I will not leave them in overnight, but will make the float adjustment and then remove them and replace with the brass plugs.

Does Moroso consider these sight plugs suitable for permanent installation?

The installation instructions do not say anything about removing them after adjustment or any warning about ethanol.  In fact, at the end of the installation instructions they say that,  "over time, the plastic Sight Plug may begin to haze over due to fuel, heat and sun exposure.  To remove this haze simply polish the plug using 600 grit or finer sandpaper."

I'll have to check, but you'd think there could be site plugs
made out of brass and glass, instead of plastic.

well what do you know, glass!
There's the solution.
