Take a torch and heat the nuts on the DHW plate till the PB blaster burns off, then use regular motor oil on the nut while it's hot, it will fume a little, but
as the oil cools the nut and stud, it will suck in a bit of the oil, do this a few times and you bmay get lucky with the nuts and studs.
I'll make a suggestion, even if the boiler's surface is very rough, dry it out, wire bruxh and grind flat, then use Permatex Ultra Black RTV automotive gasket sealer on the entire surface that the gasket touches, A THIN layer on the steel, and a thin layer on the gasket and the same on the plat's surface.
This brand of RTV is the best, I used it on my DHW plat with the OLD gasket in my AA260 5+ years ago, and it does NOT leak..
Good luck witht he gasket replacement.
