I like the one piece pan gaskets,, not so wild about the bright blue Fel Pro against a black engine, so I use grey ROL gaskets, which appear to be identical to the more expensive GM gaskets. I tried some red Permatex gasket adhesive on the front seal instead of my normal Gasketcinch. Other than the two ends, I use just a tiny bit of silicone at all 4 corners, both between the block and gasket, and also between gasket and pan, and a small bead on the bottom of the pan gasket ends.
