Where to check cylinder bore with Torque Plate?

If the cylinder was honed with a torque plate, chances are the bore is out-of-round without the cylinder head torqued in place.

If it is not available, take the measurement near the bottom of the cylinder at the point where the sleeve exits the block core.
