I'm getting ready to rebuild a small block with KB hypereutectic pistons and KB moly rings.

the rings came in a plain white box with no literature. the pistons are in the box at the machine shop getting balanced, so I don't know if there's any literature inthere with them....(I only opened the box, quickly glanced at everything then closed it up and took it to the shop for balancing)

looking online, I can find KB's page on what to set my end gaps at for their Hypereutectic pistons, which calls for a slightly larger end gap than cast/forged pistons (and I remember a SSgt who worked for me had a SBC with hypers, and his machine shop didn't set the ring gap big enough, and popped the top of his pistons off)

but I can't find anything on what grit to final hone the cylinders to. they're standard bore pistons and hte block isnt going to the machine shop, I'll be doing the hone myself.

do ALL moly rings get the same grit? I recall from reading in a book somewhere that they get finer grit than cast rings...but what is that grit? 320? that's what seems to stick out in my mind anyway, but wanted to verify.

Also, what's the best hone to use? a ball hone sized to the bore, or a 3 finger flex with the 3 flat stones that can be used for more than 1 bore size. ...does it matter, and you just pay more for the more versatile hone?
