I was hoping for some help on identifying these cylinder heads I bought for my Z. I bought them about a year ago off of ebay from a guy with good feedback, and they were advertised as non rev-up DE heads from a 2004 350Z. In the meantime, I sold my Z and these heads have been lying around in my garage. I want to sell them, but since there are a variety of VQ heads out there, I wanted to confirm that they are indeed what I thought I bought. That way someone does not end up getting screwed down the line.
I looked up the casting numbers, but could not confirm anything. Any help is appreciated.

 

def not de heads, the cam position sensor is wrong, its offset on the non revup de heads and 2 per head on rev ups. plus theres no provision for the variable valve solenoids.

its difficult to see the back of the head but looks like theres a hole in the center so mayby vq30 heads out of a maxima? that or hr heads not sure if they have anything that goes in back there sinces supposedly the sensors go into the valve cover according to the fsm.

edit:appears to be hr just missing the housing for camshaft pos sensors. vq30 dont have a hole in the back

 

Post a pic of the backside of the heads please.

 

I will take a few pics of the rear face of the heads when I get home.

I took a look at some pics of HR heads for sale in the marketplace and at first glance, they do appear to match mine. If they turn out to be HR heads, I might just have to hold on to them, since I might end up with an HR Z sometime in the near future.
