Yes, they don't advertise them at all, but Indy Cylinder Heads does indeed make them. I believe the only thing on their site that is advertised is the Chrysler intakes. You'll have to call them to get current pricing, but I think they're around 1k-1200ish, depending on options.
Never heard of a Royal Ram.
A buddy of mine has the Littlefield version of mine (they look identical with nothing more than a casting insert change for the brand name). He's a 'collector of parts', and also has 2 Indy manifolds (one tall, one short), and a Hogan blower intake (I think it's for a big chief).
The Indy castings are really stout.
Here's the Indy on RJ for sale... It's for a big chief.
