The mold for the block was made up from various pieces. The lifter valley section is one piece of the mold. Presumably there would be many other lifter valley castings with quality control numbers from 1 - maybe 15? The control number was used so that if workers on the casting or machining line spotted defects it would be easier to find the affected tool. This is common practice in any large foundry operation.
