Default Using an ej257 long block in 06 Wrx

Hey guys Iím not sure if this is in the right category but I figured you d try here before the built engine thread. Iím getting a good deal on a ej257 long block and intake manifold out of an 04 STI. I Have an 06 Wrx. While my car runs great and tuned very conservative, I do have 155k on the bottom end. Will I run into any issues rebuilding the 257 and swapping that into my car when the time comes? I donít know much about the acvs on the STI heads but from what research Iíve found, I wonít be able to use that so what do I have to do to eliminate? Here is what I currently have in the car that I will still use for the time being
VF 48
Grimmspeed top mount
1050cc injectors
255lph fuel pump
Grimmspeed EBCS
Perrin equal lengths
TGV deletes
Up/down pipe
Air pump delete
