depends...if the shortblock is dissasembled and you are using new rings..ALWAYS hone the block the the rings can seat properly..and they should be honed with a tourqe plate as well...if you can see crosshatches thats just a good sign that there isnt any real damage done to the wall's..but on the other hand, check for glaze on the walls...if they are glazed and smooth to the touch and shiney they deffinatly need a hone.

i have seen a 110k mile motor with crosshaches still in the cylinder. I would still hone it. LS1's have a tendancy to keep visible crosshatch marks, but will wear smooth. If you have it apart a light hone is good. iI would also check ring clearances if you have very many miles on it also.

unscientific answer:
...my bores showed no visable crosshatch hone markes at 38K miles...car now has 44K miles and runs great with no oil burning or blowby, etc...

...for curring piston slap, GM reccommeds dealers removal and replace the two top rings only with NO bore honing...

...if you have the shortblock dis-assembled, go for the new hone and rings...

Definitely get the cylinders honed for your new rings!! Without the proper hone, your rings may never seat and you will be left an oil burning, under-powered car.
