While you never really want scratches in a stressed area as they can 
propogate cracks iy's more than likely lasting will remove them, it actually provides 
a surface treatment similar to shot peeing but at a lower level.

If there are any engine rebuilders near you or automotive machine shops 
you'll uually find they can bead blast.  Just insist they tape the ring grooves and 
when you get them back scrub the cleaned pistons very well.
