At 6' 4" (how much do you weigh?) I'll suggest that you should contact Eagle Mike for Rising Links for your Gen 2 and possibly even inquire about using EM Gen1 Rising Links on your Gen 2. Which would be even taller.
As to seat, The 08-14 Gen 2 seat is stiffer foam but same height and shape as the 87-07 Gen 1 seats.
The Gen 2 2014.5 (&up) New Edition seat, front 1/3rd is same shape, firmness & height as early Gen 2 but rear 2/3rds is widened like a Corbin or Sargeant full height seat.
