hey guys i have a 05 S2000 and i got a complete F20 head from my friend. I was wondering if the swap is easy or if there is any fitment issues. i looked and cant find anyone that has done this swap. thanks in advance

 

The heads are the same for ap1 & ap2 other than the cams and retainers.

Note that the ap1 cams may not be the best for an ap2's powerband.

 

thanks man thats what i wanted to know. i was planning on fully building it before i put it on so it should be a nice gain
