When I get my pistons for my LS, do I have to hone the block? Or do I have to bore it to .25 mm? Or do I do both? I have 134k miles on the motor.

exactly, i recommend at least honing it when you replace pistons, and if the walls are beyond the service limit i recommend boring it 1st over

Ya listen to him, if the sleeves have flexed or aren't as straight as they should be then bore and hone then put in the pistons, or something to that effect...
