I'm not sure I would have risked it tbh, the damage a flywheel can do when it parts company from the crank is unreal. It would always be in the back of my mind. Did all the correct lenght bolts torque up successfully?
I don't think there's much chance of it parting company to be honest...
He's got 4 bolts, fully torqued, with loctite on full engagement.
He's also go 2 bolts, torqued, with loctite on with over 60% engagement.
It's not like the car is doing 10,000rpm drag runs or repeated launches with ridiculous power
