Ask a good machine shop- there's no way someone online who's never seen your block, let alone measured the damage can tell you how much you need to bore the block to clean things up.

yo calesta i wasnt asking how much to bore it out to take care of my problems cuz i have measured my block and i know my problems, i was asking what is the most u can bore it out without weakening the already weak cylinder walls of the open deck block
