I've got a set of late model, Mark V heads. Open 118cc chambers, supposedly Oval ports. Are their any manifolds out there that will work with these heads? Or am I better off to trade them for older heads? They are casting number 10114156...91-up...oval...OPEN...Gen.V & VI 454, 118cc chamber (from Mortec). Any advice here would lbe greatly appreciated.
