Try Steel Seal that is available on the Internet and eBay. Its a clear liquid that forms a glass like repair without any fillers at all, unlike Bars Leaks, Radweld or K Seal that all use fillers
Its expensive , however, around £30 plus and its best to drain the coolant system and add with new Ethylene Glycol Antifreeze and distilled water.
I tried it on my Ford Sierra with a bad head gasket leak and it lasted a year. I then went back to using the stuff with fillers, because they were cheaper and the car is still running, but does need more frequent addition of these leak sealers.
If it was just the radiator or heater matrix leaking, any of these products will give a very much longer lasting repair. A head gasket repair is asking a lot from them
