i just did a head swap on a 4g64 with a 4g63 head. I got the car to start today but its a rough idle. I dont have a pcv but i doubt that can be the problem but never know. I also dont have most of the vacuum hose connected but the fittings on the throttle body is plugged. also i believe the timing might be off a half a tooth can that cause the rough idle. by the way i have a 1g cas so i dont know if the wires are in the right cylinder. the idle seems like a iac idle but more extreme.
