I use a Clayborne, brought back to life after lots of brazing, welding, and seemingly random tabs were added by a previous owner.
It is an extermely good stand that allows the engine to be rotated axially for access to anything.
There is a wartime Ford manual of setting up a high-volume assembly line flathead rebuilding shop that shows endless rows of flatheads moving through the various departments on Claybornes, with boring and valve grinding done on the carts as well as assembly.
End adaptors allow full access for clutch and cam work, and nothing is obstructed.
