Default ej20 DOHC heads onto 2.5 SOHC NA block

can anyone provide maybe a pic of the two, i'm thinking about the possibilities of putting DOHC WRX heads on a 2.5L NA to up the redline a bit and increase the overall flow... maybe i'm way out to lunch but i can't seem to find a similar undertaking anywhere.

the car would be run NA... i'm sure EMS would be required as well

i'm just really wondering if the bolts, coolant and oil passages would line up

if i had a spare 2.5 block i could try it, but right now it's required to move my car around... the wrx heads i've got. i'd like to use the ej20 intake manifold as well(TGVs are very deleted).

opinions and experiences appreciated!!
