I would say that the 14mm would be the correct hole size, the plug thread diameter is 13 point something.  Also the plug sits in a well that is about 21mm in diameter and about 3/8 inch deep.  I am not sure that a CHT ring will fit in the well.

Can someone tell off the top of their head which CHT I need for 13B spark plugs?  Spruce sells 10, 14, and 18 mm and I'd really like to get a Spruce order in and am feeling a bit lazy and not really wanting to head out to the hanger and measure and then convert one to metric...
 
Thanks.
