This is my first time rebuilding a rotary, From what I can see from other people's post this is normal Wear on the housing. Am I correct or do these need to be resurfaced?

 

More pix please. Especially of "power" side and spark plug area.

That wear looks normal, but that doesn't mean it's a good idea to reuse them. Chatter marks like that accelerate wear. What's the mileage here? And how many more miles do you want to get out of the rebuild? If you're going for a like-new restoration, I'd look for better ones.

 

135000 mi on them I would like to get 20000 out of them by then I will put a swap motor in and do a more indepth rebuild
