3.910 + a few lines

Yup. 3.910 would be the factory unworn bore and 3.912 would be the factory maximum before you need to bore it. So, if it's 3.9113, that's still below maximum spec. Although, not by a whole lot.

3.912 doesn't require boring. That's only 0.002. A good quality honing should take care of it.
