OK I want to pop the worn 4afe out of my 91 auto sedan and put a 7afe in. It looks like it will go in mechanicaly, but can I put the sensors from the 4f in it and just wire it up to the 4a wiring and ecu? I also went to my buddies junk yard and saw an outrageous 7afe head, it didnt look like the 7afe head that I just put a head gasket under for a customer a few days back, on this head, the intake ports went downward at a pretty good angle twards the valves, I didnt see the intake that went to it but I would sure like this head on the 7afe that goes into my 91
