Also would it be possible at all to do a big valve flathead?
It's possible for sure. It'll take a small fortune in special tools to do it. But big valve and seats were pretty common. Dual valve springs with split keepers too.

The head will require clearancing, or just get this one.

I've got a small valve version.
