basically, the flycuts are only for when you are assembling the engine and rotating cams to give some space. I dont think you really need the flycuts, if you use the 45 degree mark like we do on the S4.
but , im a little superstitious so i cut them and only cut .175" on both ex and intake.
not hard to do and not that expensive.
Now, thats it.... 300ccs more displacement for the cheapest HP gains you will find, without expensive head modifications. (or crazy cam costs)
tough part is getting one shipped to you, but anderson can help here im sure.
generally, they can be found for 1000 bucks US. (*generally)
