header bolts becoming stripped help

im taking of the old header the last person put on the car for a new one i just got, but i have 1 of the three bolts out for it, and the other 2 are starting to strip, and idk if its normal for some cars but when i had my integra the bolts connected upright so the nut would be upwards towards the hood, but this i have to go underneath to get to them..... i need these off asap but does anyone know how i can get them off as they are stripped?

you can find special kind of drill bits that drill into stripped bolts to removed them but youll have to get new bolts
