Sizzler - To offset bore you have to do all the holes to do it right. Unless you have a high dollar block the cost to do that is to high in most cases. Offset boring also creates rod side clearance problems to if your not carefull. Better to find another junkyard block or buy a race block in the first place. The other thing you can do is sleeve the sucker, and I really have no problem with that, even on modified engines. I know its not popular though and most guys look down on that.
