2001 jetta exhaust manifold gasket

Hi, I have a 2001 Jetta with the standard 2.0L engine. I am about to change the spark plugs and am going to take off the exhuast manifold to do it (it looks almost impossible otherwise). I have two questions:

Where can I find the part number for the exhaust manifold gasket so that I can replace it while I have the manifold off?

Do I need anything other than the appropriate allen wrenches and sockets to get it off and then back on?

thanks

I'm sorry, I meant the intake manifold, not the exhaust

With a little work it can be done without removing the upper intake plenum. The gasket is widely available through aftermarket stores, just ask for the plenum gasket.
