Cometic gaskets

I get rid of the bottom center rivet. For whatever reason it would get pinched between the block and head on mine. When I tweaked the valve I copper coat just the sealing surfaces for the first time ever. They were new gaskets. No issues so far. Really no logical reason other than Atwood does it and my frame of mind at the time was, “I don’t want ANY issues!!!!!” I’m also not ashamed to say I throw a bit of stop leak in when it has been apart.
