OK im lost. I thought the 14cc head was for the GX160, box stock has always been based on the 196cc motor, not the 160. So how would the 14cc head ever be legal for box stock, or are you guys talking about BP here?!?
I believe if the motor came with the 14cc head in the box, and cc's are still the 26.5 min you are okay!
I do not understand though why you would use the 14cc over the 22cc in stock form. Because the 22 cc flows better.
Unless because of the smaller combustion chamber being able to get a better burn...
