The Shiver manual says 610cc for the 45mm and 90mm oil height (air gap). That would be per fork not total. The exact cc measurement is not all that important anyway.

Maybe you already know this but the 610cc bit will only get you sorta close. You have to measure air gap to get the right level.

I have 50mm Zokes, so no direct FHE but most of the comments I've seen here recommend more like 110mm oil level on the 45s. If you look around there are some pretty extensive threads on tuning those 45mm Zokes.
