Those kind of sealers are only for temporary repair and not meant for lasting any length of time, besides they also plug up radiators, heater cores and some of the smaller coolant passages inside an engine. Headgaskets are picky these days, on one rig they will hold if overheated several times and then other times one will blow if the engine one time runs just slightly hotter than normal or for no apparent reason just blow. So don't mess with the sealer, fix it right by pulling the heads, have them checked and milled and install new headgaskets.
