Torque plus angle does not automatically mean torque to yield.
Torque plus angle is intended to be more accurate than just torque where a stretch gauge is not appropriate. A torque wrench is basically measuring friction, so a lower torque reading, plus an angle is a more consistent way of reaching a desired torque.
Torque to yield bolts must be replaced.
The slight elastic stretch is what gives a bolt its clamping force and it remains tight, TTY is almost, or goes into plastic deformation, hence 1 time use.
I would just fit 10.9s, I have re used OEM bolts without problems on a subframe, including track use with no issues.
