Im still using the RS12 case (as I find it works better for me) and the standard head clearance without the shims was only 0.2mm on my engine. I know its not overshimmed and the head isnt too high. I'll post a picture of an old button head I have that I ran with just the silver shim.
Its possible that the newer Nova engines have a 0.3mm clearance without shims in which case the silver shim on its own will be fine.
I never overshim an engine. I tend to go the other way. I'll destroy whatever is necessary to find the lowest possible head clearance I can get away with. I always push my engines to the edge regardless of the cost so I know what the limits are.
