So by standard do they mean fine, or is that how they came stock? Sorry about the n00b question just curious. Im asking cause it says standard is 164 and one of my cylnders is 166. Thanks.

General rule of thumb is that all your cylinders should be within 10% of each other. Yours look fine.

A little bit of carbon build up can cause numbers to be a lil higher but your numbers are good. If your numbers were like 20 less than the standard rate then you'd have a problem.
