The most common stock head is on the left and the Dax on the right.
I instantly noticed a difference in power after the install. There was so much more compression that the clutch slipped when trying to start the engine. I had to tighten the flower nut.
I would say it's around the same gain as I had with my Manic head. You can see in the pics that the Dax head is decked and the combustion chamber is more conical, and the stock is a wider dome.
