1985 vf500f tuning help !

hey there i have an 85 vf500f i have 4-2 mac system minus the mufflers. the mac system has the front two cyclinders on the left and rear two on the right both exiting 2" pipe. both the end at the same spot in the rear, so the right side (rear) two cyclinders header is shorter. i was thing about putting a supertrapp mufflers and having less on this side to try to equal back pressure. so with the supertrapp mufflers and de snorkled air box with a k&N filter what am i looking at jet wise for the carbs. im also thinking about installing accel super coils at the same time, any thoughts? thanks !! new here and dont even know if this is the right spot but here goes.
