head swap ??s

[superu]

So I've heard swapping 2.2 heads onto a 2.5 gives higher compression and more HP.

 

Does anyone know if EJ18 heads will go onto an EJ22, or would heads from a 2.0 be better. If so what are the 2.0 options (models and years)?

 

Opinions if this avenue worth exploring. . .

Thanks,
