All rockers/valves going up and down without any problems or apparent errant noises - so I guess no broken springs.
Now it's midnight in Suburbia so I couldn't test it. We will see what tomorrow brings. Still haven't been able to install the WBO2 gauge. Maybe next week if it doesn't run with the replacement coil.
Question still open - does having the square (TFI) type coil matter?

Just as an aside....
A broken spring can still let a valve go up and down. If it's cracked or broken, it will let the valve float because the spring pressure is greatly reduced.
I'm of the mind that it's ignition too, but I'm trying to cover all bases.
