Question EJ25 head size

Can anybody tell me if the physical size of a head on a EJ25 from a 99 Legacy is the same physical size of a head from a 2.5L STi?

I bought a blown EJ25 from a Legacy with heads and I am using it to mock up a chassis that will eventually get a built STi motor. I just want to make sure that if we make enough clearance for the heads I have on the blown block, that is will be enough room for the new engine with the new heads.

Any thoughts?

Thanks for your input.
