Stock FI intake on GMs ZZ4 creat engine

I have a '86 IROC and a chance on a good deal for a ZZ4 creat engine and was wondering if it is a bolt in using stock parts or if I would need to change a lot of parts like intake and exaust manifolds computer and stuff ?

If it's a short block, it's a bolt up.
If it's a long block your going to have to check that the heads are compatible.
