If I read your question right, your trying to use the cracked block? And or one with a cracked cylinder. Which are two different things.

Did both guys look at the block/cylinder issue with there own eyes?

If ether problem is the case, then boring or just honing the cylinder is a waste of time and money. You can save time by taking a $1,000 bucks and throw it out the window during a crowded city street at lunch time.
