I have to look thru my notes which a have on this.
But If you have a block with a chamfer and the tools to check for CCs along with some clay then make a mold of the chamfer and drop it in the CC burette.
I tend to think in terms of a chamfer for a 2.11” valve that 1.5 CCs is more like it, but that hinges on what you have for a bore diameter.
