" Also for the torque specs there’s a pretty big range on the bolts, should I just do in between the two? "
Aiming for right in between is a good idea.
Torque specs are only really important for head bolts.
I never torque my bolts.
Bigger bolts, bigger wrenches, more pressure.
Too tight, they break or seize.
Too loose they fall out.
It takes practice.
