I've heard that, but didn't see any in the pictures that I looked up.

Would prefer a stock manifold though. Is there much of a loss if the injectors are sitting more up right? I would imagine fuel puddling would be less of an issue with sequencial injection.

It would have to be a thick flange that partial slips over the two manifold. It would be welded from the inside.

It would be a pain in the butt to weld from the out side with the runners being so close together.

A bolt on option is possible, but would add another gasket to fail.
