follow up so I can remember what I'm doing as I go along.
Well plans change and some Z2 Superflys with a long steerer turned up

Which means I get to keep riding my other bikes, have ~10mm extra tube to play with while also using normal stem and headsets.
So put them on last night, placed my wheels and seat post from the Rocky on to this to see what it looks like and to get some ideas.
So 27.0 is a perfect fit for the frame (as would be expected)
Red is suppose to be the complimentary colour to Green, hope not as it's hard enough to get hold of some nice stuff as it is, lol.
Question though, there is a thin lip around the top of the CaneCreek S8 headset, that a very small area to be pushing down on, I've placed a spacer I have above it so I don't damage the stem though there is still a gab between it and the spacer. Is there any reason why the lip is there ?
Suns a bit bright today, think I need to pick a better place to take pictures.
