i have come across a good set of st220 heads with im, fuel rails and injectors cheaply. i remembered it like the 3.0 heads dont quite match up the 2.5 cylinder block. do i remember correctly, and what is it that do so they dont fit?

thanks and happy easter
 
St220 3.0L heads won't have the provision with the oil return on the rear head. So it won't be a true bolt on.

Might be able to use old 3.0 heads, but no reason there.
 
I remembered like there was something. Do the old heads have the 35mm valves and ore identical in flow.to.the later inflow? Loads of them in the scrap headed here now. It's not flow in the heads I'm after.
