Hi. Can I change a 30hp Manifold into a 25hp?

Just want to know if I can make the diameter of a 30hp intake manifold small enough to fit on a 25hp engine? Has anyone of you tried this?

Kind regards...

Yes, this can be done. I have designed a tool to mill the endcastings down from 31.5mm (36hp) to 28.5mm (25hp). Id could also be done by had with a small grinder, but probably wouldn't look so nice.
