quick cylinder bore question

[natt2000]

what color should the bore of the block be? mine is polished metal in some parts, with the rest of the spots polished brown. does this mean i need to have my block bored? or is it just staining or something normal

there should be no spots where your fingernail can catch on and no gashes or unvenness

 

[natt2000]

its smoother than a babys bottom, just uneveness is color.

oh, and where would i be able to find some cheap used or new .020 over pistons?

The brown is just burned on oil.
