Ya i got those tools..dasander said:You can take the head off and not take the timing chain off. If you are trying to remove the head you will have to pull off the two camshaft sprockets (16v).
You have to remove the engine to replace the timing chain, unless you use a chain with a removable master link. either way I cannot thing of any special tools you will need. The head bolts are torque to yield, so in addition to a torque wrench, you will need a dial turn meter.
