KC vs. OG valve body

[77 cruiser]

What makes the KC different from an OG?

Is their a different KC than the one I have? Mine has KC 2 in yellow.

The only difference in the valves was the LO detent, the smallest land on the spool was .023 bigger on the KC than the OG & the next smaller ones were .006 smaller on the KC.

What are the differences in the shift valve spring free height?

Id bet the OG has a lot different governor pressure/driveshaft speed and not the same in various gears at the same speed. I dont know anyone who was able to get an OG to work consistently with similar up shift rpm in each gear at WOT
