2019 summer race.... Jadaharabi vs 318willrun

You can control the RA on finish with a grinder, depending on which grade stone used.
That looks really rough for a surface finish, I am used to seeing 63 RA finish on products we make. Super smooth.
But I work in the aircraft industry, that looks in the photos to be a RA 125 or greater, which will give the head gasket some bite.
Nothing wrong with it for the application.
