no you dont have to bore or sleeve it if you are using stock diameter pistons(most companies make lower compression stock sized pistons)....i would recommend arias or wiesco for pistons...try the forced induction forum for more info

You could possibly get away without doing it. BUT, it would not be the best idea. First of all, do you really know that the piston to cylinder wall gap is correct? Boring machines are not perfect, and neither are pistons. It is highly possible that the bores will either be too big or too small, especially if the engine is old and worn (too much clearance) or if you drop in forged pistons (possibly too little clearance).
Then there is the issue of wear. Even if piston to cylinder wall clearnace seems OKAY, there are such issues to consider as out-of-roundness and taper. For these reasons, I would not even consider using new pistons without boring. If you were willing to spring for a set of new pistons (~$500), you owe it to yourself to get your cylinders bored (~$100).
