Whittle Rings are stainless.

I don't know of any block sealing head gasket that uses anything but stainless steel or monel/inconel fire ring,

Yep.

 

Is it the separate gasket/fire ring combo that looks like this?

Okay, I'm going to ask the dumb question, how are these better than average HG's? Higher compression?

Tim if you please post part numbers.

Gasket  11044-E4621

Rings 11045-N3120

 

To answer your other question, they have pros and cons

 

Pro:  they are MUCH harder to "blow out", so they are more tolerant to high cylinder pressures and detonation

 

Con: they are MUCH harder to "blow out", so they allow you to run with more detonation.  On a poorly tuned engine this can mean breaking ring lands on expensive pistons instead of just having to replace a $40 head gasket.

The block is machined to receive the stainless o-rings

Not really - Google didn't turn up too much.  Maybe try Courtesy Nissan to see if they can scrounge a set up?
