have you disassembled 97 EJ22 heads?

the note at the bottom of page 6 of this article says all 95 and later EJ22's have roller rockers. i'm not sure when this article was written, but it has photos showing 97 solid lifter heads and the newer style t-belt tensioner. i'd assume the article is only refering to phase I EJ22's.
i'm just wondering if 97 heads have rollers & solid lifters.

this part caught my attention, too:
"...The piston, a major source of engine friction, has been coated with a friction reducing agent called Molybenum. This thin coating not only allows smoother travel through the cylinder, but also reduces cylinder wall scuffing..."
isn't the friction between cylinder walls and the piston rings? how would coating the piston help? or are they just talking about after your 97 gets piston slap?
just wondering since i've got nothing better to do at 2am on a school night...
