The plastic frame around the coolant passage distorts and the seal eventually is lost.

I got that same part number and gave it to my dealership. They ordered that gasket, and determined that whatever the deal is with the pins, they weren't compatible with my engine. I'm not sure exactly what the pins are or where they're supposed to go, but they didn't work with the rest of my engine, so they had to use whatever gaskets people used before these came out.
So no, apparently not all Series IIs have locating pins on the cylinder heads.

I'll leave open the possibility that my dealership lied to me, although it looks like they were pretty specific about their reason why the gaskets would not work on my car. If it'* just a matter of holes for locator pins, I wonder why GM doesn't make two versions of the aluminum gasket, one with pins and one without?

The thing we will have to try and verify is the differences between the earlier and later S2 3800 head-to-LIM mating surfaces. As other members do their gaskets, we'll have to remember to ask for specific pics.
