In the past I tried putting the EZ30D intake manifold onto the EZ30R and there was some interference, so the intake wouldn't sit flat on the heads. I don't remember what the interference was - this was probably 5 or 6 years ago. If I ever get my EZ30R heads back from Delta Cam I could recreate the fitment test, but I don't know when that will happen.
