A Commodore is a passion. Anything else is just a car
What the rockers do is change the ratio of lift in the valves or something. The higher the number = the larger amount of air you get into your cylinders = more bang/power.
Don't really do much by themselves as i found out but apparently do a good job when combined with a opened intake and exhaust. I've got my airbox opened up with pipes running everywhere plus a set of 1.8 ratio rockers and not much happened. I'm hoping i can say something different after monday afternoon when my 2.25" twin exhaust has been fitted
