So if im running a bigport with heaps more comp (shaved head/block and thinner HG) would it be better to run the smallport plugs?

The race cars at work run 1.1 plugs and they are extensively worked.

I always knew how to read them for motorbikes, but never knew what the extra bits were for cars, cheers
