318 Oil Pan Gasket/Sealing techniques?

Learned this from a commission mechanic friend on small block Mopars, so I know it works... Permatex high stregnth Ultra-Grey in the caulk gun tube. Apply a thin layer 1/4 inch wide bead to the pan gasket and seal surfaces and smear in place and let it skim over. Put your gaskets and seals place and repeat the process on the gaskets and seals. After it tacks up some wipe up any excess inside, and then install. We used an Hitachi 1/4 inch drive electric impact wrench to tighten the bolts with. Never seen one leak, and they're something else to get back apart.
