Wayne: The front cover gasket will normally come with sectioned replacement corners for the area of the pan gasket that comes in contact with the bottom of the front cover or you can elect to replace the entire pan gasket after replacing the front cover and its own gasket. The corners of the pan gasket are cut and removed and these pieces used. I am a proponent of the 1 piece gasket from either Victor or Felpro, they have metal insert rings at the bolt holes and prevent overtorquing the gasket and causing it to squirt out, they advertised as being reusable too. Instead of silicone sealant I like "The Right Suff" made by Permatex, it has more body and for my $$ seals better & longer.
Drain the coolant before you start and when removing the front cover gasket from the block face, cover the opening at the front of the pan if it is still on the engine block. You do not want bits of the gasket getting into the
oil pan.
