XJ 650 RJ Seca '82 - Rounded cyclinder head nut in recess - removal?

Got a picture of that gasket? I couldn't find an integrated one when I rebuilt my cylinder head.

 

Like this only in a lot better shape.

 

Thanks for that!

 

Not a problem, I'm just glad I can finally help on this site, and that I didn't throw it away yet.

 

Yes my gasket is like that also (only for Seca RJ650 model though) Got the blue line which takes the place of the original tunnel seal gasket.
I am about to re-install cylinder head, with repaired studs and bosses.
Do I have to use gasket seal please (with this type of cylinder head gasket)?
I have some red stuff, I was advised to use for my gasket cover reinstallation, which I saw on a thread a few years ago (anyone know where this thread is now please?) It was from a guy in Canada - on this site somewhere - back in 2013/4?
I don't want to install the gasket, without sealant and then find that I have an oil leak (had one very small anyway, before I removed head)
When I removed head, and old gasket, I couldn't really tell if seal had been used last time (certainly not red anyway)
Any experiences greatly appreciated........
