Can overheating damage the engine sleeves? on 1996 Nissan Maxima

Hello everyone. Can overheating damage the sleeves (cylinders) in any way? Particularly at the lower part? I'm replacing the head gaskets after running without water and my mechanic, who's never worked on a Maxima before, told me that, after overheating, engines with sleeves instead of a bored block may have damages at the lower area where it's supposed to be sealed and not let water and oil mix. Is this a real risk in Maxima Engines? It's a 1996 3.0 24v V6. I appreciate any thoughts.

Do not worrye about it . Those are not removable sleeves.

Thanks very much for the reply! What really worried me about it is the fact that this engine (VQ30DE - 1996 Nissan Maxima 3.0) is a wet sleeve engine. So it has seals at the bottom of every sleeve, which are in contact with water all around. If you can tell for sure that this is no concern on this specific engine, please reply, because you'd have saved my life! :)
