Won't the EJ25 head be overbored for the 2.2 block? Won't that leave some sort of weird squish zone at the edges? Does some welding work need to be done to fill this gap in so the 2.5 head and 2.2 block mate properly? Also, hasn't it already been shown on the CObb Tuning site that the SOHC EJ25 heads have the best flow capability of all the current heads. Why not just put the SOHC EJ25 head on the EJ22T short block?

Just curious.
