Flywheel lightening

[DaCRANEz@aol.com]

I have got my engine back together and am now rebuilding the tranny.  I am 
considering lightening the flywheel.  Anybody know how material 
(thickness-wise) 
to remove to cut the weight by 6 lbs.  Also as the material is coming off the 
friction disc side how will this affect the disengagement?  I would think 
that as the clutch fork will travel in an increased arc maybe a longer pushrod 
may be needed to maintain proper pedal travel.  TIF
