Trickflow Power Port 270 on a B block question.

Heck, I wasn't even sure TF made a B intake till a couple days ago. So I have no experience with how much metal is there, to know if it can be opened up to maxwedge.
What I do know, I described above. My TM7 has had a chunk of aluminum welded to the top of each pair of ports, to enable them to be opened to max size. The bottom of the port is okay, but bare minimum thin. Width of port seemed to be no problem.
What would have-to-be/could-be done to a 383 manifold to get it to match a 270 tf, I have no way of knowing.
As said above, the only bolt-on maxwedge B manifold I know of is from indy, and I don't know if you can even get one now.
I can post pics of my Tm7 if it'll help.....
