Can 95-98 EJ22 heads work on 90-94?

[Baddog]

I know 95-99 is OBD2 and 90-94 EJ22's are OBD1. But can you use the heads off a 95-98 EJ22 and use the IM from the 90-94? Or are there sensors in the heads that are different?

well the phase I intake manifold will inteechange, sensors will need to be swapped, but they willl work

[Baddog]

What sensors? The ones from the current heads over the 95-98 heads?

Or are you referring to the sensor on the IM

the heads for sure, if you can swap sensors from the 90-94 2.2 to the 97-98 manifold, DO IT!!! the 97-98 manifold flows better according to subaru
