A body big block back to small block

Hey all just out of curiosity I've got a 1974 dart sport that has been big block swapped to do so I used the shumacker swap mounts. When using said mounts you have to cut the riverside of the k member to level the engine. I would like to swap back to a small block so what I'm curios of is. Can I use the schumaker swap mounts currently on the car or do I have to repair my k member and use factory mounts? Thank you for any info
Big block mounts won't fit a small block, Schumacher or otherwise.
Use small block mounts and raise the mount the amount you removed.
