Summit burners are still available but according to this thread they are 1/2” shorter and from inspection, Vieluxe burners seem to be much more resistant to corrosionNope but IIRC the burners on a gen 1 Summit are the same ones. I know when Jon got my Summit I gave him extras that were in excellent shape. Maybe he can sell you what you might need

I’m going to pull a burner from my Summit 450 to confirm
Hail Mary solution may be to add 1/2” extension to each valve on manifold and order new summit burners
