Aluminum ZZ4 head with ROUND exhaust ports???

I have a set of ZZ4(L98) heads part # 10088113. They have screw is studs, and the green stripe springs. All that is fine, but the weird thing is they have ROUND exhaust ports. No D ports. Anyone have a clue on what these are?

10088113
Pretty much tells the tale

What the part # says they are, is what they are

Wouldn't get all wound up about that other, not a particularly "defining" feature or anything like that.

I for one think that is strange. I've never seen them with round ports.
