balancing.

Don't worry about your lightweight flywheel.
Unless your lightweight flywheel isn't balanced....

    Can you explain what "retune the harmonics of the crankshaft" means?

    Or was he just appalled that you'd put a heavy stock pulley on his beautiful lightened crank?

      The reason why they need the pulleys is that need to retune the
      harmonics of the crank shaft once its been balanced.
      My machinist after he knifeedged my crank he took a look at my pulley
      and looked at me and said:
      This is garbage... if I put this back up we didn't really accomplish
      anyhting cuz were just putting back some more weight.
      So I guess he got me aluminum one. From where he got it, I have no clue.

      The engine is almost complete.
      Rods and pistons are still back ordered (dammit why do they have to
      always give you a hasle with custom stuff!  

      Head will be done soon and will post pictures of it :)
      - Ported and Polished ( 2.0L 16v ) 
      - Head Converted to Solid Lifters 
      - Black Nitrided SS intake Valves and Inconel Exhaust Valves
      - Valves are .5mm oversized and 1mm back cut for better flow.

      Now I'm a bit confused on whatever I should wait for UMS or get the DTA
      unit.
      Either way I will have to look at fitting the Gm sensorsso it's a toss
      up between the $2500 CAN ECU or the $250 Can ECU ;)

      I don't think they'll be grinding any metal off of the pulleys...  My
      guess is that they bolt it together with the crank and material gets
      taken off of the crank if it's out...
