They're a 30hp or so boost to any pre-vortec headed motor, thats worth the time and money to me.
The difference between the 906 and 062 castings is [drum roll] nothing!  Some of the 062 castings had different seats installed for 3/4-1ton HD applications. Some claim that hurt flow, GM stated it didn't. I belive they don't flow any different myself.
