UPDATE: 4/2020
After using this for a while it appears that the speed 6 bore is not going to work with the speed 3 master cylinder. It creates too much pressure for the master and screws it up. You can use this guide to make your own 3an line setup but for now this is not a solution.
UPDATE 2...
I recently went built motor and installed an ACT 6 puck "zx5-hdg6 kit". The first 1500 miles or so the clutch engagement was about 3/4 up the pedal. This seemed about right and took a little while to get used to as the pedal is heavier and grabbier then stock but after no time I had it figured...
