Valves are 5.400" vs 4.86", don't know how much the pockets are raised but they're fairly shallow, not plunge cut like "normal" Stage VI's. The roof to bowl is definately higher and the short side is a good bit longer, they have a pretty nice sweep/transition from port to bowl on both the long and short sides.

Rocker stands are milled flat, they need custom pedestal blocks to work.
