iF YOU ARE GOING TO USE THE cOMETIC mls GASKET CHECK YOUR HEAD AND BLOCK MATING SURFACES FOR SURFACE FINISH.
The Cometic gasket works best when the mating surfaces have a very smooth surface - unlike the FelPro which can tolerate a much rougher surface. You want to get a lot closer to "mirror finish" for the Cometic gasket to perform better than the FelPro.
Been there.
