so i was about to attempt a tuneup, cam seal replacement, and a v-tec o-ring replacement on my 97 sh and found that one of the 8 nuts on my valve cover is stripped and just wont come off...

so sad. any ideas how to get this off and if i do get it off, how would i fix this stripped thread problem where i can have a nut there to tighten up when i'm all finished? i keep cranking with the socket wrench and it wont move up. there's a slight drag while i'm cranking also... it's not free turning.
