Not 100% sure if the mechanical rockers will like being in the hydraulically fed head. They may/may not get enough oil (could be the opposite as G63B mechanical heads were splash and splatter when it came to oiling...) but yes, mechanical lash adjusters and rocker assemblies are the way to go if you want better performance.
