you'll need a few special tools to complete this job. pulling the head shouldnt take "you" more than a few hours. But do this...determine if your # 3 valves are bent, if so, you have jumped time and need to replace your chain, tensioner and rails.
Torque specs come with the head gasket. you will need 14 new stretch blots for the head. have a friend help you lower the head onto the block.....that is do not tear the new headgasket with the sharp edges. replace your timing chain cover and seal while you are there.
