Sorry to ask the dumb questions - but why is a none valved engine better than a valved engine for turbo compound?

Second question if I may. Who is doing the best job of aluminum side plates and what combination of combustion chamber coating and seals is best for durability.

Thanks and congrats on your impact with F1.

Some Australian companies are making aluminum side plates. Google it.
