Good luck with that.
Before you grind the remains flat it may be worth another attempt to unscrew them if you've a small set of mole grips or suitable pliers. Without the head the remains of the screw won't be under tension or have the friction of the head against the bowl, a bit of penetrating oil and gentle heat may shift them if there's enough left to grip.
