Has anyone reused rotor housings that have this type of damage in the exhaust port area. I have a couple of housings with this type of damage, wanted to know if they could be used to build a not so perfect engine.
Seeing that the damage is not in the compression or combustion area could they be used if the marks are completely deburred?

I am sure some of you guys have done this before and have relative success.
Let me know.
