So, take lots of pictures, and explain your method! Cylinder fitment is key to good
power, especially on a N/A diesel.

Telescoping bore gauge.
My personal feelings on the matter of bore measurement is that it's best left to a machine shop. Why? Well, for one thing, the telescoping bore gauges are prohibitively expensive. Second, it actually takes some practise and skill before one can get repeatable measurements with such gauges. I've tried it with borrowed bore gauges, and still can't do it right. Taking the measurement is almost an art, and if you are inexperienced, it's worth paying the machine shop to check out. Besides, if it all checks out, you can then pay them $10 a hole to hone the bores, and you'll still be money ahead versus buying a hone and trying to do it yourself.
