need help ASAP. 96 ka24de into 93 s13 ka24de

[decay25]

im trying to swap in a 96 ka24de off an s14 in to my 93 s13 ka24de. i've already put the s13 manifolds on the 96 but im having trouble mounting the injectors and some part of the vacuum system that is mounted on the rear of the head. the bolts that are suppose to mount the plate have been moved. can this system be removed and still be able to pass emissions over here in south texas.? everything else seems like it would fit except for that plate. i could really use an answer asap.
