I have a pair of 1600cc twin port heads, going free. **GONE** The heads show signs of possible cracks near to the spark plug holes so I am not going to risk using/selling them. One of the heads also has a burnt out valve. I have been told the heads can be welded/repaired but not sure. If anyone wants them to try a repair or just for decoration/door stops then contact me.
