look at the sticker on the back of the motor for the engine code...
twin cam= SOHC
quad cam= DOHC... just look on the heads, and count the cams

swap the heads from your Ej22 onto a EJ25? just keep the EJ25 heads on there..

Did you mom give you an ECU as well?

'96-99 Outback DOHC, '98 RS & Forester DOHC, '96-99 GT DOHC, '99 up RS & Forester SOHC, 'OO up RS, Legacy, and Outback SOHC.

The DOHC heads are much deeper (due to four cams) and have a bigger timing belt cover. If the 2.5 engine you have is DOHC, you need the proper ECU to make it work. That could be an issue, since your car is pre- OBDII. Otherwise you could run the 2.2 heads on the 2.5 with your stock intake manifold and ECU...

did you get a EJ25 longblock or shortblock? if its a longblock then use the heads that came with it, if not then you can swap the heads from your motor.
and we still hav'nt established if the EJ25 is a SOHC or DOHC...
