What should this setting be for help with a 3 headed blade? 60?

For many multirotor heads cyclic phase is 0°, because phasing is done mechanically.
So you have to check what your rotor head require to operate correctly.
Manufacturer of the rotor head should tell you all the details.

Have a look on my explanation to find right phase:

What would the cyclic phase setting need to be on a goblin 380 three bladed heli or a oxy3 Qube?

AFAIK, both manufacturers specify that to go from their two blades head to their three blades head the only needed change is to reduce the cyclic gain.

it seems ambiguous with the spirit flybarless

Where did you see any ambiguos note?
The FBL has nothing to do differently than with a two blades head, if everything has been done mechanically... why should Spirit be different?

it ambiguous because tomas has mentioned that in some cases it doesn't need to be lowered with three blades...

Spirit has adaptive regulation that is able to tune itself to a certain degree. So this is reason, why it can fly well with the same cyclic gain.
But generally you have to lower the gain. So everything is true.
