Sorry to probably ask a stupid question

I finally bought a set and it saves you from doing a ton of math. The brand was Tusk.

I know that Z1Enterprises sells at least one set that doesn't have an 18.
If the clearances should be between 0.08mm & 0.18mm, the equivalent SAE are 0.003 inch to 0.007 inch. pretty simple really.
I don't know what sizes are needed for a 550.
