Yes those are series 2 rockers...
The 93-95 L27 had a pivot that had roller style bearings on the ends of the pivot... Actually a great way to reduce valvetrain friction without redesigning the whole rocker
I guess GM figured why reinvent it when your going to have a totally redesigned 3800 series II in 95...lol
