When we did Paul's (JpsKiller) 3ltr Head Gasket we decided to do a howto. Its rather long so please be patient. I won't be able to complete the thread in one go as there are 40+ pictures and descriptions to go though.
In the beginning take one 3 ltr engine and notice the oil sprouting from just below the cylinder head.
This task is better done when you have access to vehicle ramps as it makes getting under the car that much easier.
First, disconnect the battery and put car in ramps. Make sure that the car is stable and safe to get under.
Drain the radiator, this is how we do it. Bit of garden hose and a bucket. The hose fits over the outlet peg by the radiator drain plug.
