Hi All. I'm looking for a Cast Iron Cyl Head to suit a 1954 A7 Star-Twin, Part number 67-1063 (but stamped 67-1064) This is the larger, squarer finned type usually associated with the swinging-arm bikes. It differs from the standard A7 head in its porting, having a larger 1 1/16" intake port against the standard 15/16", Different valves and 'worked' ports to increase the flow rate. Will travel or pay postage. Please contact with any information. Thanks in anticipation. Peter. 07919-841751 or petercranwell@fsmail.net"
