In order to change the bore size on an LS1/LS6 block, the old sleeves are bored out and new sleeves are installed. One place that I know of that does this is Agostino Racing Engines who has developed a proprietary process to do it. There are several of their bored, stroked (421 cu in) engines in our club members cars as well as a turbo'd 416 cu in engine.
