At the time, they had a stock of the Batten guides to service the heads in customers' hands.
I would think there's a good market for a stock-appearing, high-flow SB head.


And the LA-X and MA-X heads OP was asking about (yes small block) were actually an RHS product. From my memory, Indy bought exclusive distribution rights. If they aren't going to have more made, they should just let RHS make them available on their own again. They definitely got good reviews when they were available.
