pictures of cyl heads. the black set has a casting number of 12562934 and the blue set has a casting number of 14097088. the blue set needs a few new exhaust seats. the black set is perfect. both sets were cleaned by machine shop recently. both sets were off fresh water cooled motors no internal corrision .
