Can anyone identify these heads?

I was aware, but these will go on a magnum 360. I found a complete donor vehicle with a running 360 and 46rh but I just wanted to make sure that I was looking at an EQ head. If it is, we have a source for these bad boys that's 100 bucks cheaper than anywhere else on the internet. I just investigated on rock auto and sure enough, it's $219 bare, and $396 assembled.
