Thats true, it seems to me that you must maintain fuel to air ratio
properly...I'm sure there can be a small deviation little leaner or little

of increase in performance its required to install the 1.25 ratio rockers.
Installing the rockers.. increases more air in the chamber allowing the
proper fuel to air ratio with increase of fuel delivery.
