The top of the sleeve is higher than the cylinder block top. (This is such a design.)
First of all with the cylinder top, shaved one.
Turn the pick test, pick up the coordinates of the center point.
As a result, the pitch of the bore was a 61mm-90mm-61mm.
I will prepare the boring head.
Chip sets the for cast iron.
The boring head allows you to adjust the protruding amount of the blade in this dial. It is a very small value of 1 / 1000mm.
At the same I've also available cylinder bore gauge for the measurement.
And it will be boring. Aim φ49.00mm.
Φ48.995mm in boring. Φ49.000mm in honing.
