Got this engine off the bay for the starting bid. Had heck of a time getting the only three head bolts out. The short ones. It is freed up and feels good. Just need a back plate for it. Be reasonable now. 
John, FYI, the Control Line Store on eBay (Bob Brooks) also sells an Allen head type complete bolt and gasket set for the McCoy 35.
