Dart Big M Head Gasket
 

Can any one tell me which is the right head gasket for a dart big m block 4.5 bore with afr heads, dart said felpro 1047 and afr said felpro 1017
thanks john

the 1047 fel is the correct gasket for salt water it has the stainless core you can use the 1017-1 if your closed cooled or fresh water.

the fel pro mls number is 1075

the cometic multi layered steel gasket is a much better option, part # is c5333-040

thanks for the help
