That is odd that there's no crosshatch. Even honed w/400 grit, a cylinder will still show of c-h even after break-in. It might help to get a good light source in there and hold the light at a shallower angle to see the crosshatching better.

Is there any ridge at the top of the cylinders? I'd want to get a bore gauge on it to see if there's any taper and to get the bore diameter. Was there any smoking or fouling plugs, or any other signs of oil consumption (might be an optical illusion but the bottom piston looks pretty sooty)? If the cylinders were glazed or the hone too fine or nonexistent, the engine would be using more oil than it should.

Have the bores been chamfered (arrows)?


Below is a #48 chamber for comparison.
