Valve spring limitations vs Cam selection

Still waiting for my block from the machine shop so my CR is calculated from piston manufacturer. Comes in at 9.27.

" "How is ICA calculated?"
you really need to work with these guys and do what they suggest
do not try and pick your own cam but know enough to be in the ballpark and keep asking questions"
......This is what I am trying to do and that is why I'd want to calculate an ICA with some of the cams suggested.
Sure, I could just post the choices here and maybe I will at some point.
