Dunno. Appears to be a bolt in an oil galley and the pressure is daylighting at the bolt head, but I dunno that there's a galley at the bottom ot that particular set of bolts.
Either that or you have the wrong head gasket, but again, I can't think of a common galley or passage those bolts enter or are really close to.
I'd be removing the heads and looking at the tracks . . because it won't heal itself . .
