I just pulled the head off my E320. I recommend using a hoist. Luckily, I was already set up in the garage with a cross-beam and come-along. I just lifted the head and pushed the car away. With both manifolds on, I'd say the assembly weighed 150-200 pounds.... too heavy and difficult to jostle around in the engine bay. It was too much trouble to remove both manifolds (couldn't... an intake bolt was overtorqued by the manufacturer!).
