My suggestion is to get a good repair manual if your going to take on a big job like this, and it's easy and inexpensive to get a high quality repair manual. To be better prepared, read up on the job you're about to perform, it will show you component locations, bolt torque settings and what special tools you'll need to replace the head gasket.
