I am old school and still like the cork gaskets. I use a bead of silicone and attach them to the valve covers to keep them in place. Then I'll set them on the heads. I tried a set with the hard rubber coating. I found them to be too hard & had difficulty getting them to seal. I actually broke the corner off of my diecast aluminum Mopar Performance valve covers over tightening them to try to get the gaskets to seal. Oh, and the black rubberized gaskets, when removed after being on for a good while come apart and leave a mess to remove. At least that's my experience!! Matt B.
