Next dab your index finger with Hylomar and smear between bored......
next get some 5amp fuse wire and cut 3 strips 50mm long and place fuse wire onto Hylomar.....
next place new gasket correcy way up and replace cylinder head and torque down.......
I learnt this trick from an old race engineer and I done many engine builds...since then and have none blow head gaskets..........
give it a try...................
