My dad has a 1959 panhead FLH 1200. He needs over sized valve seats. The machinist says they need to have an outside diameter of at least 2.016. Does anyone know where he can find these? He's checked Fog Hollow, and JPCycles, the largest size they offer is 1.990. If all else fails would it be possible to adapt a Shovel head valve seat instead. I'm sure it could cause other problems, just want to know what your thoughts are on it.
