You have a couple of options:
1) Have a machine shop manufacture you a set of delrin pucks similar to your existing VPI delrin pucks but 7/8" taller.
2) Replace the VPI delrin puck with a taller aftermarket puck like the Black Diamond Racing "thick" puck
3) Remove the existing SMF feet and use a low profile compliant footer (Herbie's Fat Dot)
In addition, make sure that your drive belt is on the lowest flywheel groove setting
