Thanks for helping,
I am building up an 88' Turbo II (S4) I bought from a friend of a friend. That brings me up to three 2nd gens
The engine was torn down to find apex failure so I bought tubs of old parts, two boxed up rotors (As seen below) and a super clean shell. I have been cleaning up what I have and gathering what I need.
I read (Probably here) that I can use the opposite faces of a rotor that are damaged and probably be okay with some mild surface stuff? The first three pics are of the one that has a bit of corrosion on it, or had.. its surface is lumpy in spots. This is how I received these.

The second rotor I have (4th and 5th pics) is cleaner but has some damage to the faces as hopefully you can see.

Last Pic: I plan on using this housing. I bought two off a member here (For super cheap)-one of the housing has the flaking over 65% of its edge. This one has just what you see here within the 2mm spec. You're educated opinions please

Thank you!

The first rotor is fine. That K stamp is normal. The second rotor, just verify that the damage dos not stand out. If so filee it flat with the surface. Just verify the clearances for the apex, side seal and corner seal slot at the spot with the damage.

Rotor housing can be used as long as none of the damaged area stands off off the surface. It is marginal but it will run.
