Looks like an older design. I wonder if that's a 70's NISMO part. I've seen pictures of an OS or OSR dohc head for the L20b and L28. I have pictures of that on my computer.
Further down that page they have a picture of a twin supercharged Viper V10! ...as if the V10 wasn't insane enough! From the front the superchargers look like turbo units, but from the back you can see they are belt driven.

http://www.datrats.com.au/page12.html bottom of this page has pictures of the OS Giken heads.

Was the Nismo L20 head available through an option catalog, similar to the LY28, or was it a race only part?

I was just guessing that maybe those were NISMO DOHC heads. Could be just about anything back then.

Here are the pics I have of the OS heads. I've never heard of the LY28 engine. The 280ZXR used the standard L28 engine... that's the only other car that was for "race"

Is that LY28 just a crossflow head on the L28 block? The distributor looks to be almost in the right position...

And that is really a 2.8L? Its not one of those Z432 engines is it?

From information I have the LY28 is actually a completely different motor with different rods, pistons, valvetrain, manifolds, as well as different mounts and bell housing as the motor doesn’t lean like the regular L-series 6. Apparently the LY head will bolt to any L-series block though.

The Z432 had the S20. Perhaps you are thinking of the 240ZR? which to my knowledge had an LY28(not 100% sure though).
