One thing no matter how the cylinder is resized:

If it is not done correctly and the shirt clearance is not exact to the new spec (about .0009 to .0012") check the book) and have near zero taper and zero out of round the OP will continue this thread with:

NOW the engine has ring rattle or piston slap noise

Bore ( to get a perfect hole) and hone to the perfect size and cross hatch is the best way to insure success

There are dozens of other threads stating 2 stroke bored or honed by a guy use to chevy block clearances and now the new piston has .003 or .004" skirt clearance with piston rattle after rebuild.
