If it's even farther out than that, probably the only thing you can do is remove the E3D from the MK4, then use a modeling knife and files, sandpaper, or even a Dremel moto-tool, to trim back the MK4 around the place the E3D mounts in it, to make the gap large enough to accommodate the E3D.  Naturally you'll want to remove that piece from the extruder head before you do that.
