Haven't reread the whole post but did the water pump get replaced recently? The pump from the early Renix 2.5L looks identical but has the impeller reversed and can cause a ton of issues. They sometimes get switched at a rebuilder.
First post says he is on his 3rd water pump. So unless he got really unlucky 3 times in a row the water pump has kind of been eliminated
The op definitely seems to be taking the parts shotgun approach without any real trouble shooting.
Me personally if I had done all that the op had done I would have pulled the head off by now. Could be something as simple as a improperly stamped head gasket to, to much rtv down one of the head bolt holes restricting the passage.
