Given the fact I was told by a well known Pontiac engine builder a sleeve would crack the head it would have been illogical for me to not ask the question.

If you have a step at the bottom, which it should have unless the sleeve is a stepped sleeve, you do not want a step at the top also. Trying to get the distance on that exact to make a perfect seal is not going to happen. With a stepped sleeve, you have a step at the top with no step at the bottom. These type of sleeves go in with less interference, and should not be used in cracked cylinders or cylinders with a breach into the cooling system.
