Engine designation/model plate or stamp location?

[duo001]

Is there a certain place on the engine to see what exact model the engine is?
Like stamped on the block or something like that?
I just want to know where the location of it is, I know I have a dohc... But I am trying to figure out exactly what year the engine is.

on the left side( header side) right where it trans meets the block there is a number

Cool thank you.
I'll take a look at it this weekend.

the hard part is determining what the number means.
