Roller Blocks

[Santeeford]

In the morning i am going to get a roller block from somebody in town. I have a 93 GT. I am planning on building a 347 or a 331 stroker with this block. How many different types of roller 5.0 engines are there and will it matter if this block is from an 85 or 86?

The roller blocks were all the same until they ended production. The year shouldn't make any difference, as far as I know.
