Help converting recipe to extract

[dierythmus]

I found this recipe for a clone I'd like to attempt (Kane Head High IPA). Can someone help with converting this to an extract recipe?

Also, a couple of questions:

1) What does "Whirlpool" refer to?
2) Can someone convert the hop BU's to oz's?

Whirlpool hop additions, are added at flameout, when your finished with the boil, but, before you chill the wort, down to yeast pitching temps. Spin the hot wort, with a paddle/spoon, to get a whirlpool going in the brew kettle, add in the hops. The hops, are then steeped, for a length of time, while the wort is still moving in a whirlpool. There is a slight bitterness contribution from the hops, instead of purely aroma/flavor.

swap the pilsner malt for extra light LME or DME
