Does the stock cylinder bore have a hardened surface or can it be bored and how much?

it can be bored... the sleeve is thin so I would not go over .030....thin sleeves tend to warp under pressure and heat if they are bored to far...blocks are cheap might be a better option than boring.

You can stay in the stock sleeve up to 2.835
