Ive ported the LD340s before, I know they can be done and I would use one but Id rather not have the port mismatch at the heads.

I didn't say use the LD340. I was talking about using it as a comparison to see if they have the same carb flange. I looked at both and it looks like they do. That WOULD answer your question. You're welcome.
