I'll say it again...I've set so many sleeves it's silly. My last T/A block came with 8 sleeves in it. First thing I did was machine them out and installed 8 new sleeves that were made form a better material.
Then, I used those up, and set 8 more. When I finally sold it, it was ready for 8 new sleeves. Set those with the latest cool sleeves and that pig is still running and the owner says I made him a smoking deal on that block.
I've done it over and over and over.
Any machine shop doing much race engine building will be setting sleeves without issue. In fact, I've set 4 sleeves in brand new 2.3 Ford blocks many times. They always make more power.
