RB30 engines only came in Single Cam configuration.They were in the Skyline & the Holden Commodore, which also had a Turbo Version, which had a stronger block, crank etc & this is the best one to get for mods.
You can now buy kits to change them to Twin Cam, & the RB25 head fits the easiest. Everything lines up, but you need different manifolds.
