Not familiar with the 5080 head.
The other two are a toss.
Do either of them have exhaust passages for EGR? I like all the 230-250-292 heads. The latest Mexican heads are heavier by far.

Whichever head you use, what is the intended purpose?
I suggest 1.84-1.94 intakes, 1.60 exhaust and perform a bolt in lump installation and then port the head. Tom
