totally agree with Bill, the engine is bored out to a press fit with about an 1/8 inch lip left on the bottom of the cylinder wall. the sleeve is chilled and pressed into the block and then the block is decked and the cylinder is bored and honed to the desired size, there is no holding in place by the head. Thin wall steel sleeves for the V8 engine are a different process. the old thin wall sleeve is broken out and a new one is chilled and pressed in. No boring is required. Model A engines did not have factory sleeves and the cast iron sleeves are only installed when a cylinder cannot be bored to a desired size.
