The baffle is already removed from this passenger-side cover (with the oil-filler neck). To allow the Jesel rockers to fit, this mounting area where the baffle bolts to the cover will need to be ground down for the front pair of rockers to clear. The driver-side cover seemed to fit with no mods. For extra clearance, you can also use a second set of valve-cover gaskets along with longer valve-cover bolts, which would help provide the required room.
