4g63 head on a 4g61t

[crvttc5r]

I have a 4g61t engine in my car but can get a 4g63 head for real cheap and was wondering how beneficial it would to swap heads. I mean i dont even know if it fits or what. i mean i think it would they are pretty close to being the same engine except for displacement. Anyway any help would awesome

I know this is kinda late, but you can swap the 63 head on your 61, but from what I hear, it will only help your top end, and really hurt the bottom.
