I'm researching putting the 4.0L head on my 4.2L engine. On the 4.2L, the O2 sensor is in the exhaust manifold. When I researched the exhaust manifold for the 4.0L Head I didn't see a location for the O2 sensor.
So my question is, where is the O2 Sensor located on engines with a 4.0L Head and Exhaust manifold?
If I put a 4.0L head and exhaust manifold on my 4.2L engine, where will the O2 sensor go?
