There weirdest thing of all is the idea that Spec C motors have one head that is the same as the regular STI (the LHS20V), but that the other side is a RHC. Perhaps Clark is onto something in suggesting there was a small "correction" by Subaru.. Perhaps a change in the coolent passages or such that warrented a new casting for the newest RAs? Does anyone know if the MY03 heads (V8) are also RHCs or LHCs?
