Flywheel Re surfacing

[Alien]

My apologies if this question has been asked before, But I have a flywheel from a 2001 S that has some minor grooves in it. My question is "Can it be re surfaced"?
The 101 project book suggests no, but that be may aimed at persuading people to buy an new one. With it being made in two pieces, I would block the movable part from beneath then clock it so its level before surface grinding.

Thanks - Andy
