Going out on a limb here..................
Major thrust - 0.150
Minor thrust - 0.120
Sides with no thrust - 0.090
That'd be for a grocery getter every day motor.

Those are good numbers after boring
I've owned a Dakota digital 1000 sonic teter for a long time now and I've used those numbers on mild 360 LA bracket motors(11.5 to 1 compression) where the owner only had that block and insisted on building it, it is still together today as far as I know with a lot of runs on it, 500+
One of the former NHRA stock World Champion 428 Ford racers said that they use .090 as the cut off on the thrust surfaces on those blocks
