The professor nailed it.
Full size Ram pick ups, certain Dakotas, Durangos.
While there are R/T versions of cars, they are NOT V8 powered.
The R/T head is no longer made or offered. F you want to step up on a Magnum head, available new is the Chink head castings and the American made Edelbrock.
Personally, I’d go with the Edelbrock head.
