The Service Manual shows a '+' next to the YC not a dagger.
Being an early engine/block, there may be more people interested in it.
Later blocks were plentiful.
And possibly the people may like the early block compared to the later ones.
But it is not a 455 HO engine. The Engine code (YC) determines what was put in/on the block.
But everything can interchange to make that block what you want.
