K20A3 Bottom w/K20A2 Head

ok first i have lots of questions..
i have a base RSX and i need more rpms to make more power and also to make my engine compatible with certain aftermarket parts.. now from what i know.. main difference between engines in the head.. because the base doesn't have highspeed cams which limits the rpm range and power.. so has anybody even heard or done a K20A3 w/K20A2 head?? i just came up with this idea myself because i need more power.. and to make my engine compatible with aftermarket cams, cam gears, etc. u got the point..
So anybody heard/seen/done K20A3 bottom w/K20A2 head??
any help or info please.. :iceslolan

To be honest, you might as well do the a2 swap.

I agree, it'll probably come to the same price and it'll be a lot easier.

and you get the 6 spd tranny

Yup.
