SR20 Head Question

[uhtjoogoorih]

So I went into the shop to work on the car a bit, took off cam caps, and saw that the camshaft on the exhaust side near the back side was seized/frozen. So when I turned car on after I got back in town, exhaust camshaft snapped in half in one of the journals. Didn't have my camera so couldn't take a picture of how it was. I'll be taking it to machine shop to see if it can be worked on. But I'm preparing for the worst and looking around to get a new head. Gonna be ordering my own valve train components. But I was wondering if the cylinder heads from the SR20DET are interchangeable with the the heads found in the SR20DE which were available for some of the Sentra SE-R, and the Infiniti g20. Looking to see if the FWD head can be used in the RWD engines. Been looking around for a little bit and couldn't really find much. It would be easier and a lot faster to source one rather than the SR20DET RWD head. Thanks in advance
