The new Design of rocker has nothing at all to do with emissions as they are exactly the same dimensions as the old ones so no cam timing or lift change takes place, the only difference is the new design of clip, as the old design is a posh paper clip, Alfa in there wisdom made the new clip incompatible with the old lifter to use these you just have to remove the new clip and use the old clips on the new rocker, You can buy new lifters in single parts its just the robbing Dealers want you to spend 500 plus quid on the bits !! this is a low revving diesel engine not a touring car engine !!!!
