First, let me state that I have not actually swapped out the aluminum CB/CL 175 manifolds onto a CB/CL 200 engine.....
So, all that I will now tell you is based on my experiences swapping carbs , insulating blocks, and manifolds on other Honda models, but the principles are the same....
Basically, the insulator block is just a non heat conductive plastic spacer, with a paper gaskets to assure sealing..Essentially a very thick gasket...
The critical measurements are the size and placement of the larger center (bore) hole relative to the mount bolt holes.....
Some blocks have all three holes on a single centerline, some have the bore hole somewhat offset from the mount hole centerline......
Some actually have a taper or slant built into them, but I believe the ones you will need are just flat.....
Many similar insulators are used on the "Chinese-Clone" and scooter engines and can be obtained in a variety of bore sizes...
Other Honda models have some that can be easily (and only slightly) modified to work.....(You'll likely have to "oval" or "slot" the mount holes)
