I have a carb/intake, cam cover, and the long bolt with washer.
The carb includes the manifold, heat stop, carb, throttle slide assembly, and spring. It is a bit updated from your K3 carb. It uses an O-ring to seal between the head and manifold. Unfortunately the mounting threads are stripped but a nut on the back side solves that problem as long as you aren't concerned with originality. This came off of a running bike and I'm sure that you will be able to use it for your bike. You might need to mess with the air screw or needle position but it should be close.
The cam covers are both a bit damaged but nothing that will make them not usable. One has a chewed up area from when my cam sprocket bolts rattled out and ground away at the cover. The other is messed up around the edges from where somebody tried to remove the cover with a screwdriver and a hammer. The first one I guarantee will work and not break if torqued correctly. The second one I guarantee will seal with a new gasket. The one messed up on the inside looks fine on the outside. Obviously it's all up to you.

Cover messed up on sealing area. I guarantee it will seal if a new gasket it used:
I also have the long bolt and a washer for the cam covers.
