now i haven't rebuilt an engine in twenty years. so i had the block bored .40 over got a master kit from RPM machine the main bearings pasti gauge @ .002 rods @ .001 i took one ring from each pack and push it in the cylinder a inch or so the rings said at least .004 and i don't have a .004 so i used a .006 and had a little play in both rings so i installed them should i have checked every single one??? do they come big and small of all the ones you check how many do you have to file? or should i take it back apart and check them all??
