A cement head, comprising a first module comprising a first module outer profile, a second module comprising a second module outer profile, a bridge comprising a bridge profile engaged with each of the first module outer profile and the second module outer profile. A wellbore servicing apparatus, comprising a first module coaxial with a central axis, the first module comprising a first module outer surface, and a plurality of first module protrusions extending radially outward from the first module outer surface, a second module coaxial with the central axis, the second module comprising a second module outer surface, and a plurality of second module protrusions extending radially outward from the second module outer surface, a bridge having an outer bridge surface and an inner bridge surface, the bridge inner surface substantially complementing each of the first module outer surface, including the plurality of first module projections, and the second module outer surface, including the plurality of second module projections, when the first module is substantially adjacent the second module and a bridge outer surface, and a retainer coaxial with the central axis and configured to substantially radially retain the bridge toward the central axis with respect to each of the first module outer surface and the second module outer surface.
