Confused? How about this setup for some B bodies around 69? 70

Older pre 71 A body with KH Used as well. My 69 does.

Pic posted in the link of the first post is correct 71 up. The “Texas valve was added to the distribution valve. Not the best setup if using aftermarket components. Loosing bleed is another issue entirely. Could be leakage or could be a poor master.
