I'm in the same frame of mind. I hear longneck could add 30hp but just find that a little hard to believe. Maybe if after a defined use the stock one is heat soaked but the aftermarket one isn't, then some differences become more apparent. And the shuttle valve has to slow things down a bit. I wish a credible source would publish a same day before and after dyno chart or some roll-on times.
