I have started biprop engines on the test stand with gox/gh2 igniters.
I prefer using the main engine propellants to minimize the complexity
of moving the system to a flight-like setup, but gox/gh2 is admittedly
very easy to light and very hot.

Does anybody know of any operational bipropellant motor inside which the
above GH2/GOX torch igniter was used? Does anybody have experience with it?
BTW, SSME used no torches but 6 sparkers (sort of spark plugs) inside each
chamber and probably more sparkers on the pad.
