You can measure in the areas just below the ridge. That’s what HRL is suggesting. Do this before you do any ridge removal to see what condition the cylinder is in. Removing the ridge just makes it easier to get the pistons out the top. Honing is done to even things up and provide a surface for the new rings to seat on. You can’t re-ring without taking the pistons out just as you can’t properly hone w/o taking the pistons out. HRL is telling you that reboreing and new pistons gets expensive. Read HRL’s post again slowly and follow his advice.
