Cylinder wall weld??
The head gasket is black right where that goobers and rasinettes weld is. The pockets where there is no filler almost connects the 2 cylinder jugs together. Just grind that out and put a good weld with a quality rod in there and grind it flat enough for the head gasket to seal and you will have a repair that will probably outlast all of us...especially an old fart like me.
