Staff Blog: "Many of our XpertAnswers.com contributors and writer's (most of which are automotive mechanics) agree that liquid head gasket sealers can work, but argue the use of water-glass or silicate based sealers on newer model engines with aluminum cylinder heads or engine blocks. Most feel that water-glass or silicate based sealers should be avoided due to adhesion issues and potential clogging with today's newer aluminum engine components."
Wikipedia Definition:
A head gasket is a gasket that sits between the block and cylinder heads in an internal combustion engine.
Its purpose is to seal the cylinders to ensure maximum compression and avoid leakage of coolant or engine oil into the cylinders; as such, it is the most critical sealing application in any engine, and, as part of the combustion chamber, it shares the same strength requirements as other combustion chamber components.
