If you use the birbath hood with any core support after 1980, the hood latch loop needs to be moved over @ 3/4" to the passenger's side.
You also SHOULD put nuts on the backside of the loop, in the hood understructure, as the new location isn't reinforced properly for the loop and is single tin thickness, so the bolts will pull out.
The safety catch location is, I believe, the same clear though to 1993 (Dangit, I have to go look now!).
As mentiond, you will need the cowl/wiper screen.
You also should change the wiper pivots, as the later pivots are taller, but the later ones just sit higher.
If you're doing it with an INTERCOOLED radiator, the radiator cap and both shroud tabs will hit in the section of understructure directly above the radiator, I just scalloped out the structure at all 3 points.
Here's the "Birdy" hood and cowl screen installed on my old Carhauler:
