B204 head on a B234 N/A

Hi all,

Just wondering if I can directly swap a B204 head from a ng900 turbo 2.0 to my ng900 2.3 N/A. Are there any modifications that need to be made, or is it just drop in?

Also, and most importantly, does the B204 head have higher compression/better airflow that the N/A B234 will benefit from? I know there are minor differences, however if there are enough pros to the swap, I'll consider it.

I'm replacing my head gasket soon and it will be no problem for me to grab another head and try it, i just need to know if it's worth it.

Thanks
