J8C sounds a bit hot to me. I’m thinking a J6J is what the OEM spec is (but I don’t have my book in front of me). Of course a J6J hasn’t been made in years. The difference between a J6C and a J6J is where the lateral electrode ends. A "J" ends midway over the center electrode while a "C" ends at the far edge of the center electrode.
I’ve been told many times that filing a "C" back to a "J" is a worthwhile thing to do, but I can’t say I’ve ever tried. Maybe this summer!
Still, "8" sounds too hot to me….
