i7-8700K has been supported since a few macOS releases ago. I have been using one for about half a year. I haven't had to use FakeCPUID since Sierra.
Which version of macOS are you trying to install?
You can try doing the install on another computer then putting a working EFI folder on to the drive and put the system drive back in to your Coffee Lake build
10.13.1
