here is some more stuff to look at if you never seen a block get all 8 holes sleeved i bore them with a step in the bottom of old bore this keeps the sleeve form moveing down at the bottom i put some 620 locktite in the step then i freeze the sleeves they go in much better cold.then when warm i cut the tops down on the sleeves there up off the deck by .010 at this point i will put the block in the mill and deck the block till dead flat. if it just one or two sleeves i cut them to 005 up of the deck and file them flat to the deck of the block.this block was out to 4.627 and hurt in 3 holes so it could not go out to a bigger bore so now we can start over again to 4.530 and go to 4.625 bore with no problems by using thick wall sleeves
