Anyone convert log style to center rise manifolds?

[El Capitan]

I’m having trouble finding availability on new logs. Don’t think centers are any better nor safer in case of ingest. From the looks of the logs if you ingest you get water in one cylinder. On the centers you can get water on multiple cylinders.

Not sure why the redesign. Any engineers here?

Anyone do this conversion on an old 350? Do you have to make any other mods?

Thanks
