I have been involved with quite a few unites that had to be bored due to damaged bores and they would always sleeve the hole and bore it back to STD. Warranty would give us a new block or a long block. PLAY SAFE!
When they sleeve the block it is a dry sleeve, they bore it out then push in sleeve bore to STD then machine the fire deck. I don't know of anybody that even makes an over-sized piston and rings. A 5.9 is a dry block, no wet liner version that I have ever seen. It is the same thing that is done in 906 Mercedes, 3126 Cat's, and 366 Mercedes. PLAY SAFE!
