Is the oil leaking around the bolts or next to them?

Looking at the shop manual for my 82 GPz1100 B2, the M6 X 1 bolts should be torqued to 87 inch pounds(these are the two small bolts next to the #1 and #4 sparkplugs).
Is the oil leaking around the bolts or next to them?
i d have to say leaking at the bolt....what does 87 inch pounds equate to in ft lbs?.....not a hell of a lot i m sure....

the seepage is at the extreme end of the head gasket on both sides right at the small bolts...how close is the closest oil route?......i was thinking of a grade 5 or better and putting a little 1194 on the unthreaded part...
Pretty sure that hole doubles as an oil route. Best to keep any sealant goop away from it. Also, good chance you will strip out the aluminum threads before breaking the bolt so the bolt grade might be irrelevant.
As far as fixing the leak...not sure. I have the same problem but only on one side of the engine. I'm thinking about taking the head off over the winter and changing the head gasket but I don't want to end up with the same result. Someone else will have to chime in with the full-proof solution.

Torque the head again, and get better bolts, and replace to replace the small ones. Those bolts are soft, as are the cam cap bolts and rotor bolt.Likely an unnecessary reminder in this case, but be sure engine is completely cold when re-torquing.
Good Luck!

If you look directly under those bolt holes, they thread all the way through... Over the last 30 years of installing and removing, the present threads had loosen up a tad...
With a slightly longer bolt (1/8 - 3/16" for example), add a washer & the bolt tip can now secure to new threads...
Just a thought....
