Motor differences - 87 vs 90

If you're looking at just the block (No intake, engine out of car), how do you tell the 87na motor from the 90na?

The 2 different injector cases right at the top. The 87 has indented writing....and the 90 has writing stuck out from the top. And you can also see the injector tubes way better on the 90
