LD340 intake manifold modification for stroker.

I am considering horse trading some parts with a fellow for and LD340, that would ultimately be going on a 408 seeing street duty. The plenum has been modified having the center divider cut almost completely out, the remaining rib is approximately 3/8" tall. Would this concern anyone? I saw the other post a member recently started about modifying and LD340 for TQ, I see this as a different mod, and so I've started a new post.
