I went through this whole ordeal......it was not fun.
Not quite.. the mounting bosses showed up on the 1983 heads, but 3 holes weren't always tapped until late 83/early 84.
My 83 had the flat mounting bosses, but not all of the holes drilled. You can just drill and tap, if necessary. But sounds like they are all there.
