Default Crank case vent?

So I've got this '92 Electra Glide Sport and the crank case vents just like my '79 Shovelhead. I've noticed later Evo motors vent thru the heads. What year did this change on the Evos take place? I'll be relying on you guys to learnt me these things until I get my service manual lol

In 1992 the engines came with the head breather cylinder heads, but the engine was still configured as a case breather.
