How much did you mill off the head?

Hey I just wanted to know how much would you charge me for a head job on an 06 R1? I an building an all motor drag bike, No NOS or turbo stuff just a tight motor. I would like to have the ports opened up, milled down flat and valve job. What kind of power gain does this give on the R1?
