The 11-inch Long type is known for its higher pedal pressure but it's likely not a lot more than the 10-inch at idle. Where it is noticeable is at higher rpm. Those flyweights load it up pretty well at the higher rpms. There's more centrifugal forces going on the larger the clutch weight & diameter gets. With that big T-87, a larger clutch won't hurt but it will slow the throttle response. It'll have good low end torque though.

You may need a bit more mechanical advantage on your actuator lever lengths.
