Stop in for a cup of coffee

So... MRGasket .028 head gaskets or Mopar .024? (i think those were the thickness) And i just want to make sure.. both are "Polymer coated" so not sure if i would copper spray them.. i always used to spray shim gaskets..
BTW.. the question isn't bout the .028 vs .024 but more if anyone knows of quality issues with either..
