Default B8HS-10 plug

So I bought a top end kit from fred at to put on my dax gen IV bottom end. The top end came with a cylinder (decked and ported), a 6.0 chamber head, cut piston, and a NGK B8HS-10 spark plug. Does the 10 refer to the plug gap? And I am switching to opti-2 pretty soon, in which people are saying that the plug will not turn light tan unless you switch to a hotter plug (b6hs) should I order some B6HS-10 plugs or what? Don't really know anything about plug heat range/plug gap stuff.
