Complete ZC head, complete intake manifold (fuel rail, injectors, etc.), throttle body, all sensors attached to these parts, OBD1complete engine harness, OBD1 SOHC ZC ECU and maybe somethings I am missing.
I'm not sure about your fuel pump or filter.
It will be more of a challenge to do this than to replace the longblock completely. And the cash difference will be minimal.
