Use the Z-101 tech sheets that Kodak provides:
The bleach and fixer are higher concentrations than regular C-41 so minilabs can process faster. The 1:00 for bleach and 2:00 minutes for fixer are what the sheets indicate. As far as dilutions go, it looks like the first doc in the Z-101 set gives some totals for the F2 kit so hopefully that will confirm the amounts. I've never used these kits so can't give you any experience based info.
