Concrete bits have a carbide tip and will drill about anything.
I broke mine at the crossover and in the head when I install my headers. It can be fixed but patience is a Must.
This is a good idea, we never thought to use a concrete bit, the bolt and nut was our original plan

Or we can look as this as a good time to install some headers, Just like stated above soak the rear bolts in liquid wrench or PB blaster penetrating oil. then remove the front dogbones, then ratchet strap the motor forward to make plenty of space to reach the rear bolts.
