The LH heads have round intake ports instead of the oval ports. I know some guys have used the LH intake on HFM cars for higher boost applications. I do not remember if the rest of the head is the same though.
According to the epc it is the same. There is an earlier version. Up to and as of but neither are the same as the .980 engine in the w124 and w129.
