.....it looks like playing with the adjustment is my go to trial and error.
IMO, reread the first sentence in post #3. Work off that.
The .060" below is not gospel.
The clutch peddle
OVER CENTER spring under the dash works in both directions.
First, it assists in peddle effort to help your leg release all pressure plate load on the disc.
Secondly. once the peddle reaches its over center position it pulls the peddle up to is stop.
You can prove this when you "toe up" the peddle and it stays up. And pushing the peddle down past center and it doesn't return.
How
I see it,
a B&B PP spring load on the fingers
should pretty much be enough to hit OC position on the pedal itself. The fork spring keeps the release bearing pulled back off the PP fingers in pedal up position and also provides tension on the adjust rod components to maintain adjustment. The correct washer has a recess for the nut to fit in and a nub/flat in the ID to close up one section of the FLEX type locknut onto the flat of the adjust rod. The fork spring might assist the peddle up slightly, but stock replacements are surely no match to overcome an OC spring.
Out of the box...
FWIW, If the Lakewood bell itself is 7.380" (stock bell length) and a 3/16" block plate is added, the pivot may be 3/16" further rearward if the Lakewood doesn't compensate for it.
If the pivot is moved rearward, you'll need to adjust the clutch adjust further out to compensate. This also causes more angle on the fork when depressed since the pivot point is further away from the fingers. In turn this can increase the potential for a bearing retainer clip to twist out of one fork tip cup and a fork tip to twist off one pad of the release bearing.
