To replace the sleeves, do not even try to press them out. A machinist will bore the old sleeves out. Then replace the sleeves. Its a hot block ,cold sleeve process and once it is in, it will be in for good.
Then they bore the new sleeve to size and hone. Not a big deal for machine shop.
If you need custom pistons or custom rings contact my friend John Noonan at Wossner Pistons. They can do what ever you need. But you have to know exastly what you need.
