Q: 8. will this head hold my canon 600mm mk2 with 1.4x convertor and 1DXMK2 rig without creep?

A: It probably will, as long as it is not too cold, the wind is not too high, and your subject is not too vertical. I have a D500 with a 200-500 (no TC), and the head is usually very solid. It crept a bit during the lunar eclipse last month, but it was 2 degrees, with a 25 mile an hour wind and the moon was almost straight up. I still got several great images.
