Transgo tf2 question

Hi there,
I'm putting in a tf2 kit in a 1987 a998
It was originally a 1 wire lockup transmission.
From a D 100, V6 truck
It's been in my 69 Dart for a couple years just time to freshen it up.
Hughes performance in Phx. Modified the factory converter to a non lockup and they raised the stall to approx 2000 rpm.
(Back when I installed it in the car.)
So should I drill the valve body like the instructions say for lockup converter or not.
I realize it sounds obvious not to, but just making sure..
I wasn't sure if it effects anything else since it still has the original valve body...etc
Thank you
