506 block question

[GSE2SCHMIDT]

A June 1st 1999 506 block, is this likely to crack? it does not have the double diamond in the valley....too soon. But I was reading that it might have the better/smaller squirters and not as likely to crack. Should I buy this one or keep looking?

ALL blocks prior to late 2001 are known to have cracking problems. If it isn't cracked now, it will later if you tow or haul heavy loads.

In my opinion, splayed mains are the only way to solve the problem.
