K24 or a2 head on a3 block?

[EP_three]

Im going to be swapping the ep this winter and really only looking to swap the heads. Trying to keep it NA. I know the a2 head will bolt up to a3 block but will te k24? Whats my best option cost/power gain ratio?

you will need k-pro. I would forget the a2 headswap. If you want to stay N/A get some cams. Either skunk2 stage I's or stage II's. Or do a vtec killer setup. But like I mentioned, you will need k-pro for a headswap.
