That is a relatively cold plug RC9YC, if memory serves.

As Aggie said, the .165 is a baseline for the floats--it is actually the setting that comes from the Factory plus or minus .003. In almost all cases, it is acceptable.

Again, street use and set up doesn't equate to track use. The levels are invariably different. For example, on a set we did for Ernie Nagamatsu's Cobra (Le Mans Top), we set them as high as we could, using a paper clip to check for float buoyancy as close to the top as could. We also enlarged the float chamber by milling out the circular casting that lies in the housing, giving us a few extra cc's of fuel. Not something that one would do for the street, obviously.
