All the parts are coming together. Almost ready for final cleaning and assembly!

On the block. The lifter bores. Seen nothing about checking other then if the lifters go in easily (they do). Cleaned with a nylon bottle brush and kerosene, but still a bit of discoloration in the bores.

Would running a hone by hand through the bores be a bad idea? Just to be sure they are nice and smooth. Or a scotch brite or 1200 grit wet-dry... or do you just wipe them off and leave 'em alone?

I used a bore brush to run kerosene then oil through the crankshaft oiling holes. Was very careful, but would it be a good idea to take the crank back to the machine shop for a final polish just before final cleaning and assembly? Afraid any minor nicks at the hole edge could cause problems. ???

Use a dial bore guage to check lifter clearance, that will determine what you need to do. Visualy inspect the crank, that is what the machine shop will do. Break the edge with a grinder at the bottom of your cylinders to keep them from scraping the piston skirts if the machine shop didn't do this. Be very careful to not let the grinder slip and hit the cylinder bore. Final job is pressure wash the block paying lots of attention to the oil gallerys. Wipe and oil the cylinders after the wash job. Before assembly wipe the cylinders with a clean white paper towel with brake clean until towel remains white. I also suggest a trail fit of everything before the gaskets/sealer goes on, its amazing what strange things pop up, RWJ

skip the hone as it likely would remove metal. I'd do as you stated: use fine paper or a scotchbrite pad with some light machine oil and some light swiping to remove any baked-on oil or debris.
