Totally agree SJC. Heat softens Loctite to allow removal. It would be no good in a Head that got so hot. Loctite 266 is equivalent to TimeSert 6020.A quick point here normal Loctite, Red/Blue will not do it because of the heat, heat breaks down Loctite you will need something a bit special such as the stuff Timesert use!
