Watch out when choosing your headgasket.
There are 3 sorts (not looking at Kometic/WRC-ones):

1) standard headgasket, 1st generation (YB0611)
2) group A headgasket
3) standard headgasket, 2nd generation (YB1261)

I'd go for option 3, these are stronger and they have extra metal rings near the channels on the corners.
