Pieces of steel in cylinder??

I agree with keeping the cylinders thick, if possible. Hopefully, none your dings are deep enough to be on the verge of a crack or a clean-up over .030, but that only gives you a maximum pit/dent depth of .015, plus half of piston clearance. If you elect to bore it, have them start with the worst looking cylinder in case it reveals a crack or split. Also, by the numbers, the CS1019r wouldn't be my first cam choice, but it actually works a lot better than I would have expected with stock valve 675 heads with a good three angle cut.
