I was looking at how much 1jz valves cost if not the whole head.

And also Which O2 Sensor works for the 1jz engine. I figured that the 87-89 02 sensors have the same plug in but sends the wrong signal. However I've heard that the 90-92 02 sensors are a direct plug in but do they send the same signal?
I've also heard that the MKIV Supra 02 sensors are the only ones that work but those 02 sensors have a 4 wire plug in but if it is that 02 sensor i would have to use i would have to disengage the heater.

If some one can clear this for me that would be great as well as give me some prices and quotes of how much the 1jz valves would cost as well as just the whole head.
