Richard Farrant Posted February 20, 2007 Share Posted February 20, 2007 Tyler, In case your cyl. head has been exchanged in the past, it is best to check the head itself. On the top face in the centre on one side there will be either a 7 or 8 stamped in, a quite large numeral. Richard Quote Link to comment Share on other sites More sharing options...
