The only way to properly fix a blown head gasket is to replace it. I have begrudgingly used some of the snake oil fixes on customer cars in the past when they wanted something cheaper and an idiot service writer agreed to try it. They are OK if you want it fixed for a month so you can sell it. If you want to keep it you need to do a proper repair.
