Ray, from my own experience of the block to crankcase joint you will have greater success with a silicone gasket of the type the Seven Workshop sell, you will also have less chance of a bead of the Permatex sealant blocking a jet or oil way. I have tried most things over the years, paper gaskets are guaranteed to leak, silicone gloop is reasonably successful but there are risks and it will eventually leak, 518 works reasonably well for a while but again will leak eventually. As mentioned the vital thing if using a sealant or silicone gasket it total removal of oil or contaminates from the joint faces, for most other joints I have compete faith in 518 or Hylomar, both are very good products and you will not get hard globules of silicone gloop blocking anything vital.
