what engine? either way its easy, if you don't knwo what you're doing be methodical and remove things in order and put them back in the same order.
if its an 8v go to VW's parts department, and ask for part number: 026 198 025 c which is the updated version of the crap cork one and come with new head studs to make it fit. it costs £11.75.
don't know the 16v part number. either engine, its pretty easy even if you don't know what you're doing.
