Default Baja block and '98 legacy GT heads

Any out there know if DOHC heads from a '98 Legacy GT will work with a 2006 Baja block?

The thing to be mindful of is the cylinder head volume and squish area as the legacy GT heads most likely are the smaller volume heads that will end up with a compression bump. I am building a ej20 turbo with the same heads and ended using thicker head gasket to reduce compression a bit for the turbo.

Yes, but will they work with your intake manifold, sensors and ECM is the bigger question........

What car is this going into? EGR, no EGR?

More information is needed. Which pistons will you use? Which manifold and ECU?

It's a 2006 N/A Baja block. I have a 96 impreza coupe that has a '98 Legacy GT 2.5 DOHC motor, but it threw a rod. I use the car for racing in Rallycross. It is using the stock 2.2 ECU and intake.
