Sticky "stuff" coming out of head gasket by spark

[my4sons]

Have an 89 sb50p that I just put new piston/rings. Going through the break in period, starts and runs well, but there's this sticky/oil type residue coming out where the spark plug screws in running down the outside of the head gastket. I pulled the head gasket and it was a little sticky on top.

I use GN2 oil and the gas is fresh, I did put a cap full of oil in the gas tank.

Any help would be appreciated, last thing I want to do is blow or damage anything after getting it running again.

Thanks!!

Just oil, every engine I have had that was tuned properly did this. You gotta remember that that oil is running through everything and out the exhaust. Do a plug chop, I guess it could be a little rich.
