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
bit richer but what power increase would the be...my feeling for that type
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.
