My son sleeve and do any block work you can imagine. From 4 cyl's to Hemis He does everything now. He just got a new machine and fixtures again last week. He has been resurfacing aluminum blocks the correct way. You have to remove the sleeves after you measure the the sleeve height at temp. of 250 degrees. Take the sleeves out square deck the block , Reinstall the sleeves the square deck the sleeves to the required needed Height above the deck . The new Dart block he is doing now. The sleeves are .003 above the deck When the block grows with heat they are zero. This keeps the compression ring sealed under High boost when hot. He also puts in inkenal wire if you are running extreme boost. Methanol and nitro motors run cooler so there is a different equation for that I would believe .
