The A12 doesnt have the lift that your A9 has so it will be easier on you springs at high speed. The A12 has a longer duration which is where the low end power comes from. I think youll be happy with the A12 and you wont loose much top speed. The cam could quite possibly be all you need. But on the sprocket I am unsure.

I'll take your insults as compliments and blame it on your lack of intelligence.
